I installed the iOS16 beta to test the new features and everything works well except the camera, which when I access it the screen is completely black. Initially I upgraded from iOS15, after restarting, turning off/on, I tried to restore the iPhone in different ways (from the Mac and from the iPhone) without solving the problem. I also tried to restore to iOS15 to rule out a hardware problem and here the camera worked correctly, so I upgraded back to iOS16 and it stopped working. The camera does not work in any application, in the Camera, in iMessage, Halide, Instagram, WhatsApp,... The controls and buttons of the camera app do work, but it doesn't take the photo or see anything.
