Chiming in... I'm having the same problem on my 14 pro. It has only happened ONCE, but interestingly enough, I wasn't even using the camera. I actually wasn't using the phone at all. I took it off the magsafe charger and the camera module started rattling very loudly for maybe 2 or 3 seconds and stopped on its own. Really hoping this is only a software issue (and that the camera sensor isn't going to get damaged if this keeps happening...)
