Control constantly crashes from a COMException

[Sebastien]

Hello, I've been trying to get the SfPdfViewer control working on Xamarin.Froms (UWP) but it seems very crash prone.

I created a new blank page with only the control inside for testing and noticed that it only doesn't crash if I put a breakpoint after the InitializeComponent call and wait for a couple of seconds. Both the XAML and code-behind are also included in the zip.

For the PDF I'm using (attached in the zip) I'm only reading it to a byte array, creating a MemoryStream instance and then loading it using LoadDocumentAsync(Stream, CancelationTokenSource) as described in the documentation. 

Here's the exception message:

System.Runtime.InteropServices.COMException: Error HRESULT E_FAIL has been returned from a call to a COM component.

   at Windows.UI.Xaml.UIElement.Measure(Size availableSize)

   at Xamarin.Forms.Platform.UWP.VisualElementRenderer`2.MeasureOverride(Size availableSize)

   at Windows.UI.Xaml.UIElement.Measure(Size availableSize)

   at Xamarin.Forms.Platform.UWP.VisualElementRenderer`2.MeasureOverride(Size availableSize)

   at Windows.UI.Xaml.UIElement.Measure(Size availableSize)

   at Xamarin.Forms.Plat​

I'm using the nugget version 19.2.0.60

Thank you in advance.
