[camera_avfoundation] Crash when taking a photo after switching cameras during recording #168134
Description
Steps to reproduce
- Run the
cameraexample app - Select a camera
- Start recording
- Switch to a different camera (this currently doesn't work because of this issue, but I will merge a fix for it shortly)
- Stop recording
- Take a picture
Expected results
Picture is taken and saved
Actual results
Crash with an exception
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[AVCapturePhotoOutput capturePhotoWithSettings:delegate:] No active and enabled video connection'

Code sample
The issue can be reproduced on the current (hash: 8d01cd9a48399d52821e35212644037bdbe8eab7) camera example app (not the camera_avfoundation example app because IIRC it blocks switching cameras during recording)
