1.20.1 Modded Single player crashing whenever vanilla nether mobs are slain.

[SmilezG]

As the title says, my modded single player world keeps crashing every time I kill a vanilla nether mob (haven't even tried with the End yet). I have no idea what the problem could be so I'm coming to the experts haha. There are 242 Mods installed, the Minecraft version is 1.20.1, forge version is Forge-47.1.0.

Debug Log:

please help :')

p.s: opening chests in the nether also causes crashing but I don't know if that's in any of the logs or not.

Does it still crash if you remove Iron's Spellbooks?

I see that mod listed all over many of the errors. I'm unsure if that's the cause, or a symptom of the real issue.

The only other mod I see mentioned in those errors is majrusz-library-1.20-4.3.2.jar so you could possibly try removing/updating that one also.

 

If it's neither one of those, then you may need to either start removing mods, or start building your pack over again adding them a few at a time, and then testing stability in between removals or additions.

I’ll try removing both to see if they’re the problems thank you
