Can anyone help explain the below crash report? It happens rarely, and it's from a remote user so I don't have access to console output. I can't reproduce the bug.
It appears to happen at SKAction.play(). Is there a way to know what kind of exception is being triggered? Anyone know what's at AVAEInternal.h:77?

it appears to be caused by the following code:
let audio = SKAudioNode(fileNamed:fileNamed)
audio.autoplayLooped = false
parent.addChild(audio)
let playAction = SKAction.play()
let wait = SKAction.wait(forDuration: 5.0)
let gain = SKAction.changeVolume(to: volume, duration: 0)
let grp = SKAction.group([playAction, gain, wait])
let rfp = SKAction.removeFromParent()
let sequence = SKAction.sequence([grp, rfp])
audio.run(sequence)
