Cannot show dialog in WPF .net Core

Following code

OpenFileDialog openFileDialog = new OpenFileDialog();
if (openFileDialog.ShowDialog() == true)
{ 
            
}

works fine in a WPF project on .NET Framework but i cannot show a dialog in .NET Core. The dialog flickers open for a split second then the program exits with: has exited with code -2146232797 (0x80131623).

This happens on any WPF .NET Core project but works fine in any .NET Framework project.
