I don't have a solid repro myself, but 2 of my customers are doing this:
Map is displayed - showing current location.
Device sleeps
Device is woken up
App crashes.
This has occurred on at least two different devices in the same way, but I can't reproduce it myself.
The devices are iPad Mini 4 - one running 12.2, the other 12.1.4. My app is using Xamarin Forms.
I get the crash output from AppCenter:
