FaceTime video is flipped horizontally and not mirroring

I'm experiencing my FaceTime video being flipped horizontally and no longer mirroring me. This is affecting me and the caller on the other end. I have tested my camera settings in Quicktime and use Zoom frequently with no issues. So this appears to be isolated to FaceTime which does not have a setting to change this that I can find. Anyone know the fix? The answer is not "the flip screen" toggle switch or whatever wrong answer google and ai give so I'm here looking for anyone with a clue. Thanks in advance!
