Face ID stopped working on 13.5.1

Update on this.

The help desk suggested I restore/update 13.5.1 it via iTunes. Did both, update first, then restore (thankfully I had a backup of my data in iTunes). Did not work. Needed a functional phone, so had to Invoke the warranty to replace the phone.

Thank you For your response, I tried all that before posting it here. I reached apple support again. Since it was right after an update, they suggested this.

will post an update once I’m done.

I reckon it was a hardware issue of some sort.
