Unobserved Task Excpetion of Type "Java.Lang.SecurityException" on Xamarin.Droid when Pick a Photo from Google Fotos App

Bug

On my Lenovo Tablet I get an unobserved Task Exception when I pick an image from the “Google Fotos” App.

Version Number of Plugin: 2.6.0.12-beta Device Tested On: LENOVO Tablet T2-A7-20F

Code:

        pickPhoto.Clicked += async (sender, args) =>
        {
            try
            {
                ChangeButtonEnableState(sender, enable: false);

                await CrossMedia.Current.Initialize();

                if (!CrossMedia.Current.IsPickPhotoSupported)
                {
                    await DisplayAlert("Media Info", "Keine Berechtigung ein Foto auszuwählen.", "OK");
                    return;
                }
                SelectedMedia = new TruckerAppMediaFile
                {
                    Type = MediaType.Photo,
                    File = await CrossMedia.Current.PickPhotoAsync()
                };


                if (SelectedMedia?.File == null)
                {
                    await
                        DisplayAlert("Media Info", "Es wurde kein Foto ausgewählt oder das Foto ist fehlerhaft.",
                            "OK");
                    return;
                }

                var imageStream = await DependencyService.Get<Interfaces.Media.IMedia>()
                    .CopyMediaAsync(SelectedMedia.File.GetStream());
                image.Source = ImageSource.FromStream(() => imageStream);

                SendMedia.IsEnabled = true;
            }
            catch (Exception e)
            {
                await MetricsManagerHelper.SendExceptionToApplicationInsights(e).ConfigureAwait(true);
            }
            finally
            {
                ChangeButtonEnableState(sender, enable: true);
            }

        };

public class AndroidMedia : IMedia
{
    public async Task<Stream> CopyMediaAsync(Stream media)
    {
        // Open the photo and put it in a Stream to return       
        var filestream = new MemoryStream();
        await media.CopyToAsync(filestream);
        filestream.Position = 0;
        return filestream;
    }
}
