I was playing for a few hours in a deformed forest and I found very few enderman (as I said in another bug I just reported) but these enderman, every time I get close to them they disappear, they don't teleport, they just disappear, they can teleport out of boats and it is completely impossible to kill them because when I hit them they disappear, so it is completely impossible to pass the game.

I think this also affects version 1.18.12 because there is nothing related to it in the release notes.
