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 ?

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 ...
