7 Ways to Fix Discord JavaScript Error

Discord happens to be the most popular online communication application for digital developers, influencers, and, especially, gamers. It is free and very user-friendly. Discord lets you create servers for your groups to communicate through text, voice calls, and video calls. You can add interactive bots to make your conversations more frivolous. 

This valuable platform was created with multiple programming languages, one of them being JavaScript. Discord is well known for not running into problems but it can not function properly at certain times. One such rare error is “a JavaScript error occurred in the main process”. This issue might sound complicated but this is quite easy to fix. 

What does it mean when you see the “A JavaScript error occurred in the main process” window?

This error window pops up when you try to launch the Discord app on your PC. Three conceivable reasons can cause the “a JavaScript error occurred in the main process” error window to pop up.

  1. The Discord settings configuration might be corrupt. This may be because the setup process may have been interrupted or crashed in some way. Resetting this setting or installing the Windows client again will help.
  2. There are administrative problems for Discord. If the Discord process runs with administrator privileges, there are chances that Discord might not function correctly.
  3. The Quality Windows Audio Video Experience service may be malfunctioning. The Quality Windows Audio Video experience service is an important process that helps stream content through the IP address of home networks. This has to start up automatically. 

Fixing the JavaScript error

The Discord JavaScript error can be resolved through seven simple methods. 

  1. Delete Discord and reinstall it on your PC
  2. Delete the Discord folder in %AppData% and %LocalAppData%
  3. Whitelist the Discord files from the antivirus software. 
  4. Change how the Quality Windows Audio Video experience service

How to solve the “A JavaScript error occurred in the main process”

As mentioned before, there are seven solutions to this problem. Each of them aims to eradicate the cause of this problem, by locating the cause of this problem and removing it in a way that this does not come up again. The methods of removal depend on the location or type of problem from/ because of which the JavaScript error arises. 

Method 1: Delete the Discord Folders from two locations – %AppData% and %LocalAppData%

There is a certain folder that stores temporary data settings configuration information. When these folders are deleted, the configuration settings will be reset, causing all problems to evaporate and the settings are set, back to default. 

Deleting the Discord folder from %AppData%

  1. Open the Windows Explorer window and proceed to this location on your hard drive

C: \Users \UserName \AppData \Local \Discord

You can also type AppData in the Run tool to open this folder.

You can also type AppData in the Run tool to open this folder.
  1. Locate the Discord folder and delete it. You may not be able to delete as a dialog box stating that some files were running and so couldn’t be deleted. You have to end the Spotify process in the Task Manager and try again if you see the message. 

Deleting the Discord folder in %LocalAppData%

  1. Open the Run dialog box. You can open it through the Start Menu or just press the Windows and R key together, on your keyboard. 
  2. Type %LocalAppData% in the field. 
Type %LocalAppData% in the open field
  1. In the open field, type in the following command:
%LocalAppData%
Select Discord in Local folder
  1. Hit the Enter Key or click on the Ok button. 
  2. Locate the DIscord folder and delete it. 
  3. Restart your PC after you delete Discord files and check the folder if it has any remnant files in it. 

These settings will not be lost or corrupt when these folders are deleted. The temporary files will regenerate when Discord is opened the next time.

Note: You may not be able to see the AppData folder because it may have been hidden. Make all the folders visible to see the AppData folder. Click on the View tab in the file explorer window and check the Hidden items checkbox, in the Show/Hide section.

Method 2: Changing how the Quality Windows Audio Video Experience Service starts up

Usually, the Quality Windows Audio Video Experience program starts running only when it is instructed to. But when this is programmed to start automatically, it fixes the JavaScript error in many cases. This has worked not just for Discord but also a lot of other applications which had JavaScript errors popping up.

These are the steps to change the startup method for this service.

  1. Open the Run dialog box by searching in the Windows Search Bar or press Windows + R key together. 
  2. Enter services.msc in the Open field and click Ok or hit the enter key to run this program.
Enter services.msc in the Open field and click Ok or hit the enter key to run this program.

Note: There are chances that you see the following message:

“Windows could not start the service on Local Computer. Error 1079: The account specified for this service differs from the account specified for other services running in the same process.”

If you see this, this is what you have to do.

  1. Open the above-mentioned service’s properties and click on the Log On tab.
  2. Now, press the Browse button.
  3. In the Enter the object name to select text box, enter your account name and choose Check Names.
  4. It will take a while to provide results. When it is done, Click Ok and enter your password, when prompted.

This should resolve your issues. 

Method 3: Remove Discord’s Administrator Privileges

A number of people who use Discord have reported that the application runs without any problem when they are not using their admin account on their computer. From this, we can infer that the problems could be coming up because of the privileges that are provided to the system administrator. The application should start up fine if you start up from another profile.

This is what you have to do, to deny Administrator permissions for the PC to access Discord. 

  1. Right-click on the Discord application file (.exe). You can click on any of the executable files in the installed location or the desktop if you have opted to keep an icon there.
Right-click on the Discord application file (.exe)
  1. Click on the Compatibility tab.
  2. Under the Settings section in the Compatibility tab, uncheck the box placed before Run the program as an administrator.
Under the Settings section in the Compatibility tab, uncheck the box placed before Run the program as an administrator
  1. Click on Apply and Ok to confirm the changes and save them. 

This should stop the computer from accessing certain permissions from the Discord application. 

Method 4: Reinstall the Discord application

Sometimes the error could come up because of some mistakes that exist in the Discord Installation files. Reinstalling the Discord installation files is a method of troubleshooting the application itself. This works for almost every application. 

There are two ways to uninstall Discord from their computer, to reinstall it.

Control Panel:

  1. Open the Control Panel. You can type Control Panel in the Windows search bar or open it through the Start Menu. 
  2. In the Control Panel, open the Uninstall a Program option, in the Programs category.
In the Control Panel, open the Uninstall a Program option, in the Programs category.
  1. Locate Discord and choose Uninstall.

Settings

  2. Open the first result that appears. 
Discord JavaScript Error - Type in Add or Remove Programs in the search bar
  1. In the list of applications, locate the Discord app and click on it.
  2. Select Uninstall, from the sliding menu under the title. 

Once you are done, you just have to run the Discord setup to install new Discord files. The Discord setup can be downloaded from the Discord Website. If everything goes well, you should no longer be able to see the Discord JavaScript error.

Method 5: End All Discord Processes

The Task Manager is the place where we go to stop processes, immediately. This is the same with DIscord. Some processes are running in the background, to make Discord function. These have to be ended to fix the fatal javascript error. 

  1. Open the Task Manager. You can press Ctrl + Alt + Delete keys and then choose Task Manager or just press Ctrl + Shift + Esc to launch the Task Manager.
  2. End all the processes related to Discord, by selecting the process and clicking on the End Task button. 

Make sure Discord is not open in the foreground when you do this. 

Method 6: Using Discord PTB

The Discord PTB is the beta test of the application. You can find this in the Discord site. Though it works just like Discord, it will not affect the Discord application itself. The beta Discord installation is no different from the app.

Method 7: Whitelist the Discord files on your Antivirus

Sometimes your Antivirus Software may have removed some files from the Discord folder during a system scan. You can program your Antivirus to exclude the Discord files when the computer is being checked for virus. When you whitelist these files, the antivirus will look over the whitelisted files or folder.
