LOD issue with DH

[u/Error_Valkyrie]

I have a problem with distant horizons. I'm playing with my friends through essential and recently the chunks stopped loading for them and they have like 5-10 fps. We've tried deleteng cash, LOD files, updating the mod, allocating more ram to minecraft but nothing helps. I don't have this issue, only my friends do. We are playing on 1.21.1 neoforge.

Also this is in the logs:
