After launching this mod with OptiFabric, an error about the inability to load textures pops up on the screen

Ok I'll try to look at that, but optifine is known to break a lot of things, use sodium instead which is more stable and more efficient than optifine

So I looked and yes it comes from optifine which is not compatible with a lot of mods, I can't do anything. so once again there are much better alternatives than optifine
