On Apple TV with tvOS 14.4, once Apple Music access is enabled, the following commands will cause an app to crash:
let songStoreID = "900032829"
let musicPlayer = MPMusicPlayerController.applicationQueuePlayer // [1]
musicPlayer.setQueue(with: [ songStoreID ])
musicPlayer.prepareToPlay() // <-- crashes here [2]
musicPlayer.play() // if skipping [2], it would crash here instead
In the Xcode console log, I note these messages:
// [1]
[APSLogUtils] [AirPlayError] APSCopyPairingIdentity:627: got error 4099/0x1003 NSXPCConnectionInvalid
[MediaRemote] Error fetching local receiver pairing identity (OSStatus = 4099)
// [2]
[SDKPlayback] applicationQueuePlayer _establishConnectionIfNeeded timeout [ping did not pong]
Note: It does NOT crash when using MPMusicPlayerController.systemMusicPlayer.
