Switching to/from tabletop mode causes the underlying SurfaceView to destroy and recreate its Surface, but the Camera doesn't know its been destroyed. This is a known issue with SurfaceView in Compose. See: https://issuetracker.google.com/275157240 To workaround this issue, detect when the folding state enters or leaves tabletop mode and manually invalidate the CameraX SurfaceRequest so it will generate a new one.
