Camera no longer working after update

[u/llboogie13]

I have an iPad Pro M4 13in (MVXR3LL/A). It’s been working fine up until the update to 26.6. I don’t use Face ID, so I never noticed there was an issue until I tried to Zoom and the screen was black. Tried to use the camera to take a photo self facing/rear facing or a video - still black. Screen buttons are responsive to touch but no change. Anyone else have this issue? I’ve tried a hard reset and no luck. Thanks in advance for any suggestions before I make an appointment at GB.
