It's not a crash, the error shows up when I try to join my server. The server starts up fine, client boots up fine. I join, then get kicked and this is the only message out of place.

The issue was survival plus. For some reason for 1.19.2 the latest version has no problem playing a single player world, but there's issue with servers. Just downgrade to the previous version for 1.19.2.
