Why did this crash?

[static juniper]

forge 1.20.1
atlauncher
custom modded

Steps to recreate: Go into the big vast end after defeating the end dragon, where better end biomes spawn. Randomly I crash there but it mostly happens near the green forest biome from better end, although there could be a completely different reason idk, also i can use betterend with forge cuz of sinytra.

i think this is fixed by reinstalling(?) im also not sure

and yes betterend should already be in the modpack

Uh its a custom modpack

And by reinstalling u mean reinstalling better end?
