Same here, ony minor code changes, no third party added since my last successfully uploaded testflight 3 days ago, using React Native here. Can't help thinking it's wwdc22 or ios16 related ...

Almost the same error, while trying to set Audio Session to AVAudioSessionCategoryPlayback. I've never faced this issue before iOS 16, and it does not seem to happen all the time: AVAudioSession_iOS.mm:2370 Failed to set category, error: '!int' Not sure what changed in iOS 16 ... Any idea ?
