Realm crashes before finishing loading

When I join a realm, the moment the realm shows the “creating” message, minecraft just crashes. I have been told from players in the realm that the message of my player joining appears and I appear in the realm timeline. I have tried deinstalling/reinstalling minecraft, leaving the realm, getting banned, nothing works. I can play on realms from the same account on another device. This bug affects all realms except, somehow, a realm I joined after the bug started. I can join this specific realm with no issues but not the others.
