My iphone 12 pro camera not working after updating to IOS 18.3

I updated my iPhone 12 pro to IOS 18.3.1 and my back camera and flash stopped working. I forced-shut down the phone and it didn't do anything. I now updated to the newest IOS 18.3.2, hoping it would fix the problem, and now it says it can't verify if the camera is a genuine part. It was working perfectly fine until the update. This seems like a software issue not communicating well with older iPhone cameras. This phone has never been serviced, it has all original parts. I hope Apple can address this issue with a new update that can communicate with the hardware of older phones. So many posts here about having this same issue since the update. No, this phone is no longer in warranty.
