When breaking a portal controller on a complete portal structure, the game crashes. If I break any other portal frame block, thus disabling the portal first, then the controller can be safely broken. Crash log is attached.

Edit: I reproduced the same bug in a fresh 1.18.1 install with no other mods. Here is the crash log.

I get this on 1.18.2 aswell, the client crashes but the server is fine.
