Face ID Not Working After 15 iOS Update on iPhone 12

Hi, I’m getting a FACE ID is not available or not recognized when I try to use it on any app or to unlock my phone, yet in the settings I can set up my Face ID recognition.

It stopped working all of the sudden, I haven’t dropped my phone or anything. The issue started happening two days ago, but I had updated to iOS 15 about a week ago, so I cannot bear to think it’s related.

Any advise?
