WCR: ImageDescriptionGenerator::DescribeAsync returns InternalError

[riverar]

Describe the bug

The ImageDescriptionGenerator.DescribeAsync() method, for unknown reasons, has started returning InternalError across reboots, updates, etc. Might be caused by a Windows update?

Phi Silica, Text Recognition (OCR), Image Super Resolution, Image Segmentation, and Object Erase are unaffected.

  Status: Complete (or similar)
  Description: Swirly blue whatever (or similar)

Code

private async void Button_Click(object sender, RoutedEventArgs e)
{
    if (ImageDescriptionGenerator.GetReadyState() == AIFeatureReadyState.EnsureNeeded)
    {
        var result = await ImageDescriptionGenerator.EnsureReadyAsync();
        if (result.Status != AIFeatureReadyResultState.Failure)
        {
            {
                throw result.ExtendedError;
            }
        }
    }

    ImageDescriptionGenerator imageDescriptionGenerator = await ImageDescriptionGenerator.CreateAsync();


    var file = await StorageFile.GetFileFromPathAsync(@"C:\Windows\Web\Wallpaper\Windows\img0.jpg");
    using var stream = await file.OpenAsync(FileAccessMode.Read);
    var decoder = await BitmapDecoder.CreateAsync(stream);
    using var softwareBitmap = await decoder.GetSoftwareBitmapAsync();
    using ImageBuffer inputImage = ImageBuffer.CreateCopyFromBitmap(softwareBitmap);

    // Create content moderation thresholds object.
    ContentFilterOptions filterOptions = new ContentFilterOptions();
    filterOptions.ResponseMaxAllowedSeverityLevel = new TextContentFilterSeverity(SeverityLevel.High);
    filterOptions.ImageMaxAllowedSeverityLevel = new ImageContentFilterSeverity(SeverityLevel.High);

    // Get text description.
    var languageModelResponse = await imageDescriptionGenerator.DescribeAsync(inputImage, ImageDescriptionKind.BriefDescription, filterOptions);

    Debug.Print($"Status: {languageModelResponse.Status}");
    Debug.Print($"Description: {languageModelResponse.Description}");

Thanks @riverar, this is a known issue. A fix will be released soon.

@connorMicrosoft I don't mind if you keep known issues open or closed, but can we be consistent? My other known issue is open #5352

Also will that fix go out via WU or are you saying a fix is required in WinAppSdk?
