The most common cause of this issue is corrupted Discord files, which can occur due to incomplete installations, interruptions during updates, or conflicts with other software. Other potential causes include issues with permissions, third-party modifications like BetterDiscord, and outdated system drivers. Now that we know the reasons behind this issue, let’s follow the methods to resolve it.
1. Delete Discord Folders
Deleting the AppData and LocalAppData Discord folders can reset the application’s settings and resolve the JavaScript error preventing Discord from opening.
2. Change Startup Type of Service
If qWAVE (Quality Windows Audio Video Experience) is not running, it might cause errors, including the “JavaScript Error Occurred in the Main Process”. Setting it to start automatically ensures necessary dependencies for Discord are always available.
3. Run Discord Without Administrator Privileges
Administrative permissions can sometimes cause conflicts with system security protocols or other applications. By removing these elevated permissions, Discord operates under standard user privileges, reducing potential errors.
4. Reinstall Discord
By downloading and installing the latest version, the app is restored to its default state, eliminating previous bugs or glitches that interfered with its launch. Reinstall Discord by downloading the latest installer from their website, executing it from the Downloads folder, and following the on-screen instructions. The JavaScript error should be resolved.
5. Close all Discord Processes
When Discord’s processes are closed through Task Manager, it ensures that no remnants from previous sessions interfere with a fresh installation or re-launch. This termination of active processes can eliminate conflicting issues. If some Discord processes cannot be ended, use Command Prompt to terminate them.
6. Use Discord PTB
Discord PTB, the Public Test Build, is available on the official Discord website. Installing it allows for separate testing and resolves the conflicting issue without affecting the regular Discord installation. Download Discord PTB from here. It is similar to the regular Discord and functions in the same way.
