Attempting to remove a dimension crashes the game while saving.

[Alceris]

I added a new dimension via chat command, didn't want it anymore so I removed it, however at that point doing anything that makes the game save (such as pausing) crashes, and then when I go back into the world the dimension is not removed. Fabric version 0.16.7, Minecraft version 1.21.1

Can you post the crash report

Not without just pasting the text into a comment, assuming this broken website will even let me do that much.

Since I can't put the actual file in here, here's what seems like probably the most relevant part, the rest is just system details.
