iPhone flash light and back camera not working

I completed the iOS 17.3.1 update two days ago and ever since then my back camera and flashlight won't work. I have turned my phone on and off, completed a reset, completed a hard reset, and completed a factory reset and NOTHING is working. I have not dropped my phone and it is in no way damaged, this problem literally only started once the update was completed. Looking for advice on what I can do.
