How to fix SIGABRT crash in Xamarin Forms - xamarin.forms

Question

StackTrace:
NavigationRenderer+ParentingViewController.Dispose (System.Boolean disposing)
NSObject.Dispose ()
NavigationRenderer.Dispose (System.Boolean disposing)
NSObject.Dispose ()
DisposeHelpers.DisposeModalAndChildRenderers (Xamarin.Forms.Element view)
IDisposable.Dispose ()
FormsApplicationDelegate.UpdateMainPage ()
FormsApplicationDelegate.ApplicationOnPropertyChanged (System.Object sender, System.ComponentModel.PropertyChangedEventArgs args)
BindableObject.OnPropertyChanged (System.String propertyName)
Element.OnPropertyChanged (System.String propertyName)
Application.set_MainPage (Xamarin.Forms.Page value)
PageModelCoreMethods.SwitchOutRootNavigation (System.String navigationServiceName)
BasePageModel.<NavigateToLoginPage>b__74_0 () // I think the problem is in this method
NSAsyncActionDispatcher.Apply ()
(wrapper managed-to-native) UIKit.UIApplication.UIApplicationMain(int,string[],intptr,intptr)
UIApplication.Main (System.String[] args, System.IntPtr principal, System.IntPtr delegate)
UIApplication.Main (System.String[] args, System.String principalClassName, System.String delegateClassName)
Application.Main (System.String[] args)
This is the stack trace for a SIGABRT crash I'm getting in my iOS app using Xamarin.Forms 4.4.
I think the issue is coming from this method:
async protected virtual Task<bool> NavigateToLoginPage()
{
await LoginProvider.Clear();
Platform.BeginInvokeOnMainThread( () =>
{
CoreMethods.SwitchOutRootNavigation(CoreApp.LoginNavigationStack);
});
return true;
}
because it's the last method that was called before the crashing II'm assuming but I'm not sure how to fix it. I've looked at some solutions online like:
MonoTouch SIGSEGV crash using navigationcontroller and searchdisplaycontroller and https://forums.xamarin.com/discussion/6546/finding-the-cause-of-sigsegv which I think are related, but they don't match my case exactly..
Does anybody know what to do about this?
Thanks!
