How do I use a camera-facing script and an animation at the same time?

Sorry for my unfamiliarity with the forum and for using a translator.

I currently have a character looking at the user (main camera) with a script (controlling the head and eye movement) and animation, but the character’s head is rattling. I’ve applied an avatar mask to the animation layer with the head part disabled, but the same problem is happening. Any answers would be greatly appreciated.

I don’t know what you mean by rattling, add a video and what setup you are using else no one can help
