New crashing (MC 1.20.1)

[habsunemigu]

Hi! I've got a modpack with about 56 mods that has, up until now, been running pretty well. Starting today, any world i try to open causes minecraft to crash. It isn't the game itself- the main menu opens up fine. 

I tried changing the ram allocated with both the minecraft launcher, and the forge launcher. No success with either. I tried deleting the JEI folder and letting it remake itself. No success. I tried turning off multiple mods. No success. I tried turning off JEI incase that was the issue. No dice.

If you need to know specifically which mods I have installed, let me know, and I'll send them all to you.

I've included the very first crash log. Please let me know if there's anything I can do!
