[UWP] Getting random exception updating the image

[Marco Negroni]

Good morning,

i get random exceptions updating the image in the SfImageEditor:

  The parameter is incorrect.

  The control does not currently have a CanvasDevice associated with it. Ensure that resources are created from a CreateResources or Draw event handler.

Is a UI Xaml generated exception, stacktrace:

   at Microsoft.Graphics.Canvas.CanvasBitmap.LoadAsync(ICanvasResourceCreator resourceCreator, IRandomAccessStream stream)

   at Syncfusion.UI.Xaml.ImageEditor.SfImageEditor.<GetImageStream>d__406.MoveNext()

   at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()

   at System.Threading.WinRTSynchronizationContextBase.Invoker.InvokeCore()

Code:

                this.Dispatcher.BeginInvokeOnMainThread(() =>

                {

                    this.sfImageEditor.Source = this.ProcessCapturedImage(stream);

                });

The same problem on multiple computers.

Xamarin Forms 4.7.0.1351

Syncfusion 18.3.0.40

Please it's urgent because we are in production.

Thanks in advance

I think that the problem is related about using of tasks.

How can i wait until the sfimageeditor has loaded the image in order to do something else? Ok there is the ImageLoaded event, but how can i wait it?

Thanks
