In what environment did the problem occur?

My multiplayer server that I was running

What went wrong? (Crash logs don't go here)

My friend joined my server running origins, he was slime in 1.17 but that mod is no longer supported for 1.18, so when he joined, his normal size and the size he resets to is a slab tall.
