Game crashes when player tries to load singleplayer world, but can join a multiplayer world like normal except the server will also say the same error while still being playable.

I can't help you if you don't tell what kind of errors you're getting

gadlewlog.txt

Sorry to bother you again, but I tried building the current version with gradlew and I'm getting some errors.

Fixed

Redownload the repo, there's some files that shouldn't be there

Sorry if I'm bothering you (I might be doing this completely wrong "gradlew build"), I've tried redownloading the repo and trying both 1.18.2 and main branches. But it still gives me errors when building both but with different errors.
main:
gradlewtxt.txt
1.18.2:
gradlewtxt.txt

redownload it again, I just deleted some stuff that should've been deleted way before
