Custom Character constantly shakes forward and backward also rotates when you turn your camera in first person


The image above is the character.

So basically I’m making a horror game and it has horror characters, but there is a problem that when I actually put on the character on the player who is the monster it begin shaking both the camera and the character also when you turn the camera it feels like it is being slowly dragged backwards. I don’t know how to fix this. I tried hipheight, collision control, mass manipulations, everything. If anyone has anyone other option or question I’d be happy to answer or try.
