[Forge 47.2.20 - 1.20.1] Crash due to "Exception Generating New Chunk"

I don't know why it's crashing, I don't think I have any conflicts or out-of-date mods (outside of a few datapacks). I also tried it with the beta versions of Quark removed and the previously mentioned datapacks disabled  (https://pastebin.com/F1G0QFy4) and it was still a no-go.

Make a test without wythers

still crashes, different worldgen/biome mod affected

Maybe one of the "Better" structures mod is causing issues with BOP/Terralith

Remove the stucturemods like BetterFortresses, BetterJungleTemples etc one by one

[aliveinthescreen]

disabled them all, and it still crashed: https://pastebin.com/DcF44sNZ

And without BOP and Terralith?

[aliveinthescreen]

that solves it! i tried disabling only one of them and BOP froze my game while Terralith crashed once again and threw another exception with RegionsUnexplored. 

i'm trying the biome mods on a fresh profile and it seems like they all work together, so it's probably a different mod that's causing the crash...

Update: It was Cyclic. Looks like people have also encountered the same problem as me and reported it to Lothrazar's GitHub already, so hopefully it'll get patched out soon.
