Block save corruption

So i've been experiencing crashes when joining a survival paper server on 1.21.11.

It pops up with a little message over the inventory bar but it crashes to fast to see what it is.

When I delete the server world folder from the Voxy folder in .minecraft it doesn't happen for a while until I restart my PC.

I had an issue where in my singleplayer world some blocks in the LOD Chunks are appearing as other blocks for example Water appearing as Magmablocks.
Looking at the crash log from this i'm pretty sure this is the same error but it just doesn't crash the game on singleplayer.

Here is the log, if you need any other information i'm happy to help out!

Start with the crash path at Mapper.java:238, especially getBlockStateFromBlockId, then follow ModelFactory.addEntry and ModelBakerySubsystem.tick. Reproduce using the affected multiplayer or single-player world and inspect whether saved block IDs exceed the available list. Done means rendering no longer crashes and LOD blocks are mapped to their correct block states.
