Not much to say, trying to open the mod's selection menu crashes the game outright, and dunno what might be causing the conflict, and if it can be fixed on your side.

Same error +1, but I'm using a model I used in 1.12.2, not sure if that's the problem. Also don't know if it has something to do with other mods in my modpack. I'm using the 1.16.5 remake version.
It's my fault. Models for CPM and CPM remake different.

Confirmed. I have same error.
