After trouble shooting my phone remotely with apple support, and they performing a remote diagnostic scan that said my phone was in perfect health, they set up an appointment at the Apple Store for me.
The Genius at the Apple Store did an advance diagnostic scan that did show that my TrueDepth camera had an issue. Unfortunately it was an out of pocket repair of $279 since my 13PM was out of warranty and I did not have AppleCare. Repair took 1 hour 20 mins. I was told by their genius that *IF* Apple announces a service program for TrueDepth cameras on the iPhone 13s, then my paid repair would be eligible for reimbursement.
