An exception occurred while rendering the control

Hello, I create new project with Prism Quickstart template and I can’t preview using Visual Studio Community for Mac. This is a error: It doesn’t work on Android as on iOS. The plugin is correctly initialized. This code is in AppDelegate.cs:

   public override bool FinishedLaunching(UIApplication uiApplication, NSDictionary launchOptions)
        {
            Rg.Plugins.Popup.Popup.Init();

            global::Xamarin.Forms.Forms.Init();
            global::FFImageLoading.Forms.Platform.CachedImageRenderer.Init();
            global::FFImageLoading.ImageService.Instance.Initialize(new FFImageLoading.Config.Configuration()
            {
                Logger = new Accesos.Services.DebugLogger()
            });

            // Code for starting up the Xamarin Test Cloud Agent
#if DEBUG
            Xamarin.Calabash.Start();
#endif
            LoadApplication(new App(new iOSInitializer()));

            return base.FinishedLaunching(uiApplication, launchOptions);
        }

and this code is in MainActivity.cs

 public class MainActivity : FormsAppCompatActivity
    {
        protected override void OnCreate(Bundle savedInstanceState)
        {
            TabLayoutResource = Resource.Layout.Tabbar;
            ToolbarResource = Resource.Layout.Toolbar;

            base.OnCreate(savedInstanceState);

            Rg.Plugins.Popup.Popup.Init(this, savedInstanceState);
            global::Xamarin.Forms.Forms.SetFlags("FastRenderers_Experimental");
            global::Xamarin.Forms.Forms.Init(this, savedInstanceState);
            global::FFImageLoading.Forms.Platform.CachedImageRenderer.Init(enableFastRenderer: true);
            global::FFImageLoading.ImageService.Instance.Initialize(new FFImageLoading.Config.Configuration()
            {
                Logger = new Accesos.Services.DebugLogger()
            });

            LoadApplication(new App(new AndroidInitializer()));
        }
    }

I using Visual Studio Community for Mac 7.5.4 (build 3) and Xamarin Forms 3.1.0.637273. What could be the problem? Thanks a lot

Figured out a workaround if you’re using prism. Add this prop to your App.xaml.cs: public bool IsDesignTime => PlatformInitializer == null; Then in RegisterTypes method bypass RegisterPopupNavigationService at design-time: protected override void RegisterTypes(IContainerRegistry containerRegistry) { if (!IsDesignTime) { containerRegistry.RegisterPopupNavigationService(); }

This workaround has stopped the issue for me. Thanks.
