[CURRENT ISSUE] Camera spins too quickly

I am having issues with my mouse controls. When turning the camera, it spins ridiculously fast to the point I can't control it at all. I can't change the angle of the camera without it being very difficult to get it to stop while in the direction I want it to be. I am also having major problems in CAS when trying to click and drag body parts to change their shape/size. This feels like any movement is exaggerated so it's impossible to get the shape and size of anything how I want it. Because of these issues alone, I haven't been able to play because it just isn't enjoyable in the slightest. I have tried moving the files out so it creates all new ones, and have reinstalled the game entirely from new. Neither of those things have fixed the issue so I am looking for things I can try next.
