I have various apps that use the front or back camera and intermittently the capture manager/AV session freezes. This doesn't appear to be a media services reset issue. Even if I detect the interruption and try to restart the session it won't start. I have to go to background-foregound-background-foreground and then try starting the AV session again and then it might work. I've also noticed this in other apps like my Bank of America app when scanning in a check for deposit. I've reached out to Apple filing a bug report but they say they can't reproduce the issue. This has been happening on all versions of iOS 13 up to iOS 13.1.2 on all devices from iPhone 8/X/XS/XS Max/11/11 Pro & 11 Pro Max.Jun 5, 2019 at 6:49 PM – FB6123417iOS 13 AVCamCaptureManager and AVCaptureVideoPreviewLayer now stalls for no reason or error.
