Some sort of world corruption or something that causes a data leak.  Whenever the chunks around (3000, 3000) are rendered in the data leak (idk if thats the correct term) begins. The world basically stops though, breaking blocks doesnt actually do anything besides make the block disappear, commands stop doing stuff, etc. When you leave the game gets stuck on saving world, and after closing Minecraft and reopening the world, you end up a few seconds before you rendered the chunks. For some context as to the contents of the region, it was a mini game that worked fine until it didnt and started doing that. It has command blocks and structure blocks. We have tried solving this in multiple ways, we have disabled stuff like command blocks, we have also tried deleting the chunks with outside tools and the problem persists. And as it just causes the game to die, it's not really possible to actually know what the problem is.

Steps to reproduce:

1. Import and open the linked world
2. Teleport to 3000 100 3000: /tp 3000 100 3000

Observed result:
The server seems to freeze and there is a memory leak.

Expected result:
The game functions normally.
