Net 8.0 + MS Toolkit, MVVM, VS 2022, android emulator 11 API 30

I’ve a listview based on a ObservableCollection of class

public partial class ADVImage : BaseModel //<= extends ObservableObject
{
    [ObservableProperty]
    private int _ADVId;
  
    [ObservableProperty]
    private string _description;

    [ObservableProperty]
   private ImageSource _imgData;
}

here I’ve a command

public partial class ADVModel : BaseModel  //<= extends ObservableObject
{
    public ADVModel()
    {
      Images = new ObservableCollection<ADVImage>();
    }

   [ObservableProperty]
   private string _titolo;

   [ObservableProperty]
   private string _testo;
 
    public ObservableCollection<ADVImage> Images { get; set; }

  [RelayCommand]
  private async void AddImage() //Button in page "Add"
  {
      try
      {
          var result = await MediaPicker.Default.PickPhotoAsync();
          if (result != null)
          {
              if (result.FileName.EndsWith("jpg", StringComparison.OrdinalIgnoreCase) ||
                  result.FileName.EndsWith("png", StringComparison.OrdinalIgnoreCase))
              {
                  var newFile = Path.Combine(FileSystem.CacheDirectory, result.FileName);
                  using (var stream = await result.OpenReadAsync())
                  {
                      using (var newStream = File.OpenWrite(newFile))
                      {
                          await stream.CopyToAsync(newStream); // <=== HERE
                      }
                      
                      ADVImage aDV = new ADVImage();
                      aDV.ImgData = ImageSource.FromFile(newFile);
                      aDV.Description = "New image";
                      Images.Add(aDV);
                  }
              }
          }
      }
      catch (Exception ex)
      {
          // The user canceled or something went wrong
      }
  }
}

When I reach the point where the stream has to be copied I receive this error:

“System.ObjectDisposedException: ‘Cannot access a closed Stream.'”

But why? I’ve never accessed

In android log I cannot find any error related…

Tryed to download MAUI official samples fron Github and copy-paste code from “PlatformIntegrationDemo”.. same issue/same error …

No solutions working.. chaged Mediapicker with FilePicker (same issue)
