Encountering Discord's fatal JavaScript error typically indicates a conflict between Discord and your current system settings. Below are key settings adjustments to resolve this:
Check GPU Acceleration Settings
Discord's GPU hardware acceleration often causes conflicts:
- Open Discord User Settings
- Navigate to App Settings > Advanced
- Disable "Hardware Acceleration"
- Restart Discord immediately
Test basic functionality post-restart to verify fix.
Verify Administrator Privileges
Permission issues can trigger runtime errors:
- Right-click Discord shortcut
- Select Run as administrator
- Check "Always run as admin" in Compatibility settings if recurring
Administrator mode often bypasses JavaScript execution blocks.
Examine Network Restrictions
Corporate/school networks commonly block WebSocket connections:
- Attempt connection via mobile data
- Confirm if and domains are whitelisted
- Disable 加速器/proxy during troubleshooting
Firewall interference frequently manifests as JavaScript runtime failures.
Update Critical Components
Outdated dependencies cause compatibility errors:
- Install latest Windows/MacOS system updates
- Update graphics drivers via device manufacturer
- Confirm Discord is updated to current stable build
Reboot after updating all components before retesting.
Reset Discord Voice Settings
Corrupted audio configurations may cascade to JS errors:
- Access User Settings > Voice & Video
- Disable "Automatically determine input sensitivity"
- Select different input/output devices
- Click Reset Voice Settings
Audio subsystem failures are common JavaScript error triggers.
