IPhone SE 2020 Front facing camera not working

IPhone SE 2020 "Selfie" camera is not working. I get a blurred image of the standard forward facing view then it resets to that view

I am running IOS 14.7.1

Also the main camera has begun occasionally turning to black screen - this is usually rectified if I close the camera app down and restart it.

Can anyone advise on a fix please?

thanks
