I updated my iphone 15 pro max with the latest ios. Version 17.2.1 then my front camera is not working

If the Front Camera issue is attributed to the iOS 17.2.1 update, it would imply that every device which underwent the iOS upgrade should experience this problem. In other words, if the root cause is indeed tied to the software update, one would expect a universal manifestation of the Front Camera issue across all devices that were updated to iOS 17.2.1.
