[Bug]: generating new worlds takes forever

[quackkky]

What happened?

i have a modpack with around 200 mods, and before adding the ice and fire mod generating new worlds took like 5 minutes max. after adding the mod this seems to be a lot longer. i left my pc for 2 hours and the world was still only at around 26%.

(i had to use pastebin for the log because i couldnt fit it in there, the maximum is like 65k letters

Minecraft Version

i tried fixing the problem by generating a world without ice and fire and adding it back after generating, but now i cant find or spawn any dragons, not with /summon or spawn eggs. other creatures work fine though
