Fit Method, The asynchronous operation has not completed.

Hello.
Please Help!
I try to compile the code from example
this link

I run it, but on this line:

// 3. Load Images with in-memory type within the IDataView and Transform Labels to Keys (Categorical)
  IDataView shuffledFullImagesDataset = mlContext.Transforms.Conversion.
           MapValueToKey(outputColumnName: "LabelAsKey", inputColumnName: "Label", keyOrdinality: KeyOrdinality.ByValue)
          .Append(mlContext.Transforms.LoadRawImageBytes(outputColumnName: "Image",
                  imageFolder: fullImagesetFolderPath,
                  inputColumnName: "ImagePath"))
           .Fit(shuffledFullImageFilePathsDataset)
           .Transform(shuffledFullImageFilePathsDataset);

i get error: System.InvalidOperationException: 'The asynchronous operation has not completed.'
Please Help!

Hi,
after upgrading the NuGet package from v1.5.0 to v1.5.1, the exact same exception happens also in the taxi fare prediction sample (https://github.com/dotnet/machinelearning-samples/tree/master/samples/csharp/getting-started/Regression_TaxiFarePrediction):

var trainedModel = trainingPipeline.Fit(trainingDataView);

Exception thrown: 'System.InvalidOperationException' in System.Threading.Channels.dll
An unhandled exception of type 'System.InvalidOperationException' occurred in System.Threading.Channels.dll
The asynchronous operation has not completed.
