This error can occur for a variety of reasons, from corrupt Discord configuration files to overactive antivirus software blocking the application from loading. To fix the Discord JavaScript fatal error in Windows 10, you need to perform the following steps.

What causes fatal JavaScript error on Discord

Incorrect installation: Incorrect installation causes this error because not all system files are extracted and installed when installed incorrectly.

Antivirus software: Sometimes the antivirus software on the system marks files in the Discord folder as infected files and therefore blocks the use of the necessary files.

Corrupt configurations: Configurations are one of the major causes of a fatal JavaScript error in Discord, as corrupt configurations prevent data packets from synchronizing properly, leading to a fatal JavaScript error.
