iphone 7 both cameras intermittently not working even after installing 14.0.1

The camera app will show just the controls and both cameras wont work. When I restart the phone it will work consistently but then stops again. When I try a FT call the front camera seems to work fine but when I switch to the rear camera It says the camera is being used by another application. My phone has plenty of memory available. This started when I upgraded to iOS 14. I tried the 14.2 Beta to see if the problem had been addressed. I then restored and have 14.0.1 installed. My flashlight works fine which leads me to believe I have having a different issue than others. Also of note my camera was replaced at an Apple Store about a year ago and I have had no issues with it until I installed 14. Any help would be greatly appreciated. Thanks in advance.
