LocationDisplay in Background Mode Crash Application

[FeichiShih]

I created an application in Xamarin Forms(iOS) using ArcGISRuntime SDK that listened to GPS location update in the background mode, however, if LocationDisplay is enabled in the MapView (with LocationDisplayAutoPanMode.Recenter), the app would crash when switching into background mode. I have also tried creating a custom location datasource for the LocationDisplay to not call UpdateLocation in background mode, but the error would still occur. Does anyone have any idea where this error came from, and how to get around it? Many thanks!

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by y
our application.

I'm having the exact same problem with all the latest ecosystem updates.
