Which game? I'm suspecting encrypted. 2022.3 does not use metadata v31. In fact no unity version that is released uses 31.

The game is called Pocket Ants Colony Simulator, i downloaded the apk from Apkpure. If it's encrypted what can i do?

Actually, stand by. It would appear unity HAVE bumped to version 31 for completely incomprehensible reasons in a patch version of 2022.3. Looking into it

Ok, latest github actions builds should work
