Being in the End causes the world to freeze, crash, and rollback 10-30 minutes.

In our Realm, one of our members went to the end islands to raid end cities. Suddenly the realm completely lagged so badly that it completely froze. It stayed frozen for about 30 seconds before crashing entirely. Then, when the realm boots back up, we get on again. The realm is now rolled back about 30 minutes before the crash. Now, every time that player tries to join, the realm freezes, crashes, and rolls back. They are now unable to play on the realm and it’s really upsetting. We were really confused about the cause of the crashing until today. Today, 3 other players went to the end to go raid end cities. Then suddenly the entire realm froze, crashed, and rolled back. Turns out that one of the players who went to the end is now causing the realm to crash every time they join as well. By now we were convinced that it was the end dimension causing the players to be unable to join and somehow crashing the realm. We tried to play on a standard, non-realms world as well and got the same results.

The first player was on Xbox and the second player was a mobile player. I doubt that the device being played on causes this bug.
