Hi @carson.zoom,
Thanks for your replay. I need to say this please check Zoom SDK in Latest xCode 11.2.1. There is in crash issue in UIAlertView. I think you are using UIAlertView. In Latest xCode 11.2.1 --> UIScene class not supports UIAlertView. So App get Crashed. I am 100% sure, I am not use UIAlertView in my applications. I got this crash while calling zoom SDK. So Please check your SDK with Latest xCode 11.2.1 OR make support zoom SDK in 11.2.1.
Let me know your thoughts. Thanks 
Another question:
When meeting window appeared. I got this message in above audio section,

settings?.disableDriveMode(true)
settings?.topBarHidden = false
settings?.meetingInviteHidden = true
settings?.meetingShareHidden = true
settings?.setMuteVideoWhenJoinMeeting(false)
settings?.setAutoConnectInternetAudio(true)
My needs are --> Audio is need to connect automatically with out any user interaction in meeting window.
