I played this game a while back and I remember not running into any issues with the camera, but after trying it again I recently noticed at least in the introduction bossfight my camera is sort of permanently locked on?
I am playing with m&kb if it matters.

It's not actually locked on but acts identical to as if it were, actually locking on makes no difference whatsoever.
I cannot move the camera at all unless I boot my sensitivity to the highest, at which point I can barely move it before the game forces it back towards the boss again.
It's to the point of making it near impossible to do anything, with the camera constantly spinning me in circles underneathe the boss while I have no way to control it at all.
I recall being able to move the camera freely in whatever direction I wanted previously.
