App crashes in IOS when switch from call dialer to app

[helendeguinion1]

STR:
1- Select the emergency/operator call button
2- Launch the call and have it answered
3- Set the Eyenation back in the foreground while the call is still on

RESULT: The application will crash as soon as it's set back in the foreground

Device: iPhone XS Max - 15.3.1

I use the AppLifecycleState.resumed to handle the switching but it does not work in IOS works fine in Android though.
