C# WPF binding bitmapImage to Image control [duplicate]

I tried different methods from existing posts but I am not able to update an image into the Image control. If I execute the code below directly from the view cs, it works fine (so don't pay attention to .Convert method, so the format is ok). However, I am not reaching the image update from another class.

The issue seems to be the OnPropertyChanged event, where the code executes the 'set' of the _displayedImage object properly, but when the 'get' is triggered, the bitmapImage has errors... Why if is the same object?

ViewModel:

//Image displayed
private BitmapImage _displayedImage;
public BitmapImage DisplayedImage
{
    get { 
        return _displayedImage; }

    set {
        _displayedImage = value;
        OnPropertyChanged("DisplayedImage");
    }
}

Xaml:

<Image x:Name="ImageViewer" Source="{Binding DisplayedImage}" HorizontalAlignment="Center" VerticalAlignment="Top" Stretch="Fill"/>

Code to update image:

Bitmap bmp= new Bitmap(@"C:\test.jpg");
    
RunVM.DisplayedImage = Utilities.Instance.Convert(bmp);

Update 1:

When the set is triggered, _displayedImage has the proper content:

After that, when the event is triggered, _displayedImage has errors:
