1.20.1 1.20.1 Crash

[Kiwi_Tea]

Hello...I got a crash, "The game crashed whilst rendering entity in world Error: java.lang.IllegalArgumentException: Duplicate delegates"

In game I was walking upstairs in a house, and it suddenly crashed on me. Now it keeps crashing when I try to enter that world.

I tried to give more RAM by changing it to 4...I'm not really wanting to get rid of any of the mods I have if possible.

I'm absolutely clueless about crashes and whatnot...can anyone tell me what's gone wrong?

This is the pastebin crash report Here

Let me know if I need to include anything else

Make a test without Optifine - looks like Optifine is running into a rendering conflict with alexmobs

There is a CombJelly in your area/house which is causing this issue
