This error can happen if there is a bug in MainWindow.xaml not detected by the XAML compiler

For example, if I set a wrong resource, like

 <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush2}">

instead of

 <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">

I get this error
