The Eerie Mojang Office Party event causes crashes
I have been playing on the mojang office party event server and have happened to have at least 3 game crashes so far. It doesn’t seem like they are caused by a single thing like opening a dialogue, but happen at random times.
It might be caused by trying to open leaderboard billboard signs, which don’t open and then cause the game to crash not too long after.

Steps to try and reproduce:
1: Launch Minecraft bedrock 1.21.50 and login to your account.
2: Click the event join button on the left side of the main menu, and join.
3: Play around on the server, participating in the minigames or opening dialogues, until a game crash happens.

Observed result: The game will randomly crash

Expected result: No game crashes or disconnections from the event server.
