I think that I got the same thing. My crash report is related about your report (See below)?

also when you go higher than the buildlimit in the nether

Can confirm, it crashes when a player/mob is above build limit or below build limit.
Happens in all dimensions.

FWIW, here’s another related log: https://pastee.dev/p/BVg9eVFp

In my case, it looks like a bee was down too low.

Seems to happen with any entity going above/below build limit.(mobs, players, items, boats, etc.
