Fatal Javascript Error In Discord

The fatal javascript error on Discord usually appears when you are launching the application. You will be greeted by an error window that reads “A javascript error occurred in the main process”, terminating the main process and crashing the application before you can launch it. The error box usually contains a lot more information such as the cause of the error and the path of the file which is causing the issue.

If you are also facing this issue, you won’t be able to launch the desktop client without fixing it. While most users rely on the web client of Discord until the problem fixes itself, you should try to fix the problem by yourself. It is quite easy once you understand what is causing the problem. There are a few things that cause the javascript error in Discord which are common in a lot of cases.

What Causes Javascript Error In Discord

The javascript error in Discord is quite a common appearance and you can narrow down the reasons to any of the ones mentioned here. While the reason might be different, if you try out the solutions designed to work for these reasons, there is a good chance that you will be able to fix the problem in a jiffy. Here are some common reasons behind the fatal javascript error in Discord.

1. Problematic Configurations

The main reason behind the javascript error in Discord, or many other javascript based applications for that matter, is problems with the configurations of the desktop client. If there is a problem with the configurations, the data packets cannot synchronize with the cloud service. Thus, the application won’t be able to communicate with its servers, causing the javascript error. And thus, the application would terminate itself until you try to fix the problem yourself, or until it is fixed automatically by Discord developers.

2. Interference By The Antivirus

A lot of times, people face the javascript error on Discord after installing a new antivirus program. Since a lot of antivirus programs consider javascript files as threats, some try to block or quarantine the important files from Discord’s installation folder, causing the fatal javascript error. If the problem is caused by an antivirus program in your case, it is quite easy to resolve it. You can either try launching Discord after turning OFF the antivirus, or prevent scanning of the Discord installation folder altogether.

3. Corrupted Installation Files

If you are not able to launch Discord since its installation in the first place, the main reason in your case could be improper installation or corrupted installation files. It is also a pretty common occurrence since the installation files can get damaged while they are downloading. Or, the application might fail to properly extract the important system files at the time of installation, resulting in the fatal javascript error. In such a case, you should simply try reinstalling the application.

1. Uninstall And Reinstall Discord

First and foremost, we will suggest you uninstall the program and reinstall a fresh package from the official website. If one of the crucial installation files, or the installer itself is corrupted, there is not much you can do to fix the problem. So, reinstalling the software is always a faster and more prominent way to fix the problem.

  1. To uninstall discord, first you will have to search “Apps and Features” in the Windows 10/11 search bar.
  2. Now, you can see a list of all programs and software installed on your computer.

  6. Now, head over to “www.discord.com” and get a new installer from the website.
  7. Once it is downloaded, install the program by following the instructions provided in the installer.

2. Turn Off The Antivirus

As we mentioned earlier, the fatal javascript error can be caused by an antivirus scan, whether it be Discord or any other application. It usually happens because of the real-time monitoring scans of the antivirus that constantly look out for malicious executable files. So, this process might as well cause the fatal javascript error in Discord.

To fix that, you should try launching Discord after turning OFF the antivirus program. You don’t necessarily need to uninstall the program at all. Almost all antivirus programs offer a temporary shutdown option that terminates all of its processes for the time being. You can select whether you want to kill the process for a few minutes, until the next system reboot, or permanently from the available options. The steps might differ based on which antivirus program you are using. We will suggest temporarily disabling the antivirus and see if it is causing the fatal javascript error or not.

3. Delete Discord AppData Folder

The AppData folder on your Windows computer saves the local data and cache of all the programs you are installing in your computer. So, removing the folder for a particular program from the AppData directory will simply remove all personal user configurations and temporary files created by Discord. So, if you have recently started facing the problem, it might be the right solution for you.

To do that, follow the steps explained here:

  1. Press “Windows Key + R” to open the “Run” window.

  4. Here, you can see a folder named “discord” which contains all of your user configurations and settings.
  5. Now, all you have to do is select the “discord” folder and delete it.
  6. Perform the same action by running the %localappdata% command in the Run window.
  7. After that, restart your computer and launch Discord again.
  8. If the app launches now, it will be reset to default settings. You will also need to login with your account credentials again.

4. Check Antivirus Quarantine Folder

If disabling the antivirus program did not help in your case, it is possible that the program has quarantined one the executable files from Discord’s installation folder, causing the fatal javascript error every time you launch it. The quarantine feature of an antivirus program is basically a middle ground where the suspicious files are not deleted from the system, but are kept disconnected from all other programs and blocked for execution.

This is a very helpful feature as you can check the deleted files and see if the program has deleted an important file from one of your installed programs, i.e., Discord in this case. Accessing the quarantine folder is not that difficult and you can find detailed instructions for the same on the official support page of your Antivirus program.

Once you find the file, simply click remove the file from the quarantine section and select “Allow on system” or similar option on the prompt window. While you are at it, you should also add Discord’s installation directory to the exclusion list of your antivirus program.

5. Try Discord In Administrator Mode

Another way of fixing the javascript error on Discord is to run the application in administrator mode. It simply bypasses the restrictions and allows all of the executable files to run in administrator mode, possibly fixing the fatal javascript error.

  2. Right click on the shortcut icon and click on “Properties” from the list of options.
  3. Now, head over to the “Compatibility” section and check the “Run this program as an administrator” box from the window.
  4. Now, click on “Apply” to save the settings and then click on “OK” to exit the window.
