iPhone 13 says back camera is “not genuine”

My iPhone 13 is saying that I am not using a genuine Apple back camera.

If you’re wondering why this has happened, it’s because my back camera (or at least, one of the lenses) is cracked.

I have never bothered to get the camera repaired as it has never caused any issues, but for some reason, it now says I am not using a genuine back camera. (see included screenshot)

Once again: I have never taken this to any repair shop I know, and this just happened tonight.

This won’t stop me from using my iPhone, but it will certainly cause an experience decline. Not to mention, a pretty pricey repair if I end up get the camera fixed.
