A UAC (User Account Control) prompt will appear to confirm if you want to run this program as an Admin. You have to choose the Yes option. After Discord boots up well, you can do the following to save time afterward:

  • Firstly, you have to right-click on the Discord executable.

  • You will find a check box “Run this program as an administrator” under the Compatibility tab. Lastly, choose it and click on Okay for accepting changes.

After following the aforementioned process, you don’t have to manually run Discord as Admin next time.

4. Installing Discord Test Builds

Even after trying all the above methods, if the Discord app is not starting then you should switch to PTB(Public Test Build) Discord version. It is basically Discord but has an experimental build to it. This version will store and use data separately so you will not have any problem running PTB Discord alongside the regular one.

The link for downloading Discord Test Builds is PTB Discord.

5. Using Discord Browser Version

The last method we are discussing to fix Discord’s JavaScript Error is not going to fix this issue. But it will connect you with the servers and your friends with most of the services of the Discord desktop application. Some of the services are chatting, video calling, and stream screen, which are similar to the app. Your streaming experience can become a drag if your PC does not have enough RAM capacity.

The official link for the Discord browser is Discord Online.

Reason behind the Discord JavaScript Error

There are two most prominent reasons behind the Discord JavaScript Error, i.e., while starting Discord after your system boots up, or while Discord installs an update automatically. A dialogue box will appear saying “A JavaScript error occurred in the main process”, “A fatal JavaScript error occurred” or “Uncaught Exception: Object Has been Destroyed”. You will be able to read the detail regarding the error in the dialogue box. But only experts can examine that information.

Let us explain the debugging information in layman’s terms. It means:

  • Discord’s internal settings may have become corrupt: This means that the installation of Discord is the problem. Therefore, you can solve it by resetting the settings or reinstalling the software.
  • The service Quality Windows Audio Video Experience is not active: This function is close and critical to Discord and other important services of the program. So, you have to ensure that it auto-starts on boot-up.
