In a modpack I was making I encountered this graphical/texture issue and isolated it to your mod, don't know why exactly its happening but here you go

Same, narrowed it down to this mod.

Lol same here. Sometimes it works, sometimes it doesn't. I've managed to load the world without this issue a few times. Somehow???

I will try to figure out why this is happening.

same problem for my modpack !

I have found a similar issue with Chisel. Looking into a fix.
