System.ArgumentException: 'E_INVALIDARG'

I'm working with a provate project. When starting my WPF app, i'm getting strange exception even though the app is working perfectly.

Exception thrown: 'System.ArgumentException' in Microsoft.Windows.Shell
E_INVALIDARG

I could not figure out where excatly the issue is. It's thrown at this

var applicationUtils = _rootDiContainer.Resolve<ApplicationUtils>();
_rootDiContainer.Resolve<ThemeUtils>().SetThemeFromSettings();
_rootDiContainer.Resolve<MainWindow>().Show(); //thrown here

Do I need to be concerned?
