[BurkusCat]

Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:

1. Use advanced navigation by resolving a service to decide the first navigation:

burkusMvvm.OnStart(async (navigationService) =>
{
    var appStartupService = ServiceResolver.Resolve<IAppStartupService>();
    await appStartupService.NavigateToFirstPage();
});

2. Observe crash

Expected behavior
The application allows you to resolve dependencies to decide on the navigation.

May end up being fixed by #15

Reopening as it still appears to occur in some projects

Closing again as it turned out to be some custom, platform specific WinUI code in a project that was causing the crash
