Resolve Exit Code 0 Crashes on the Launch Screen

Understand Exit Code 0

Exit Code 0 during launcher startup typically indicates a silent failure in mod initialization—often caused by Mixin version mismatches. The game closes without a clear error message, making diagnosis difficult.

Apply the Fix

1. Install this compatibility mod

2. Relaunch Minecraft

3. The mod ensures Mixin 0.8 loads before other mods attempt initialization

Verify Success

If the crash was Mixin-related, the launcher should now proceed normally and load the main menu. If you still encounter Exit Code 0, check your crash log for non-Mixin errors. The compatibility mod specifically addresses Mixin version conflicts; other mod incompatibilities may require different solutions.
