My textures in the minecraft title screen is missing. found that it happens when I try to use optifine with Fabric mods.

The mods that I use :
Malilib
Litematica
Tweakaroo
Optifine

I wanted to use malilb, litematica and tweakaroo with optifine by using the optifabric mod and I've done that in the past for pevious MC versions. The issue popped up for 1.20.1. any one know a fix ?

I cant login to the server either, the game crashes with the following crash error

Same here

That's because of Fabric API 0.86.0, Downgrade to Fabric API 0.85.0 that it will run fine, I already reported this issue here #1123
