Solution 3: Delete Discord’s Temporary Files 

When you open or edit something in the Discord app every data is stored in AppData and LocalAppData.

To delete the AppData and LocalAppData follow the steps:

  1. Open the “My Computer” in your desktop and go to “Local Disk C” (Default disk where you have installed your windows.)

Solution 5: Change Windows Audio Video Experience services settings

Window Audio Video Experience service must be enabled to run the Discord properly. In default it is set to Manual, we can change it to Automatic if we are facing the javascript error. Changing it to Automatic not only fix the Discord Javascript error but also fixes the javascript error for other programs as well. So, to change it follow the steps carefully:

  1. Type Control + R in keyboard to open run dialogue.
