Alright, this is quite complicated. When breaking a pot in the new trial chambers on java edition 23w45a in the big hallway room with spawners, a structure void dropped out. I was able to obtain a structure void in survival from this. I honesty have no idea how to even begin to figure out how this has happened, so I'll leave it up to everyone who sees this bug to figure out.

How to reproduce:

Break a pot in the new trial chamber structure inside the hallway with multiple floors and spawners.
