The Fix
There is a client crash caused by things on contraptions wanting to save data, but the Create mod being broken in the logic and casting incompatible types, an inteface ChunkAccess vs LevelChunk class.
That issue itself was later fixed in the original mod itself, I just backported it to the 1.20.1 version.
I have an already assembled jar, but you can also assemble the fork manually instead.
