Werewolves with distorted faces

I have this issue as well. I have seen other people with it that say it is because of CC, but I do not have any CC in my game.

Both my character and Greg look like this. Greg looked normal to begin with, but then next time he spawned, his face was like this. My character looked normal during their first transformation, then next time they were broken.

I have tried repairing the game, playing without mods and loading the game from before this happened. It keeps happening anyway. One fix people have suggested is to go to CAS and unlink the forms and randomize the werewolf form, but that fix does nothing in my game.
