When I go near a certain place, it’s crashing me.

So when I was working on my realm, when I was gonna go do the command block stuff it seemed to crash. I asked my friend to do it after and he didn’t crashed (he’s on windows) but when I teleported to him it crashed me out.

When I did this in a copied world, I continuously teleported to the place and nothing work even when I was 200 blocks away from it. After I removed all of the ticking areas, it seemed to crash when loading into to the world.

Steps to reproduce:
#This rarely happens, so I don’t have a way to reprodouce.
Expected Results:
The game will act normal, and not crash.
Observed Results:
The game keeps crashing whenever I go near or on the area.
