How to stop using the beta launcher | Minecraft: Java edition.

Optifine has a known bug at the moment, causing it to crash with exit code 0. Thankfully the fix is pretty simple. The crash is caused by Optifine looking for a maximum launcher version of 2.2.1, while the beta launcher is 2.2.2. As a result, to fix it, you’ll need to leave the beta. Follow the steps below to switch back to the release version.

Leaving the beta won’t affect worlds or other save data. However, if you’re worried about losing them, make a backup before following this guide.


Open the launcher and click settings in the lower left.
