WinUI 3 App.g.i.cs Autogen File breaking?

I am trying to create a WinUI 3 Application and I added some code and now the autogenerated file App.g.i.cs throws a break. Here is the code that breaks it, and e, doesnt have a stack trace App.g.i.cs

#if DEBUG && !DISABLE_XAML_GENERATED_BREAK_ON_UNHANDLED_EXCEPTION
            UnhandledException += (sender, e) =>
            {
                if (global::System.Diagnostics.Debugger.IsAttached) global::System.Diagnostics.Debugger.Break();
            };
#endif

#if DEBUG && !DISABLE_XAML_GENERATED_BREAK_ON_UNHANDLED_EXCEPTION
            UnhandledException += (sender, e) =>
            {
                if (global::System.Diagnostics.Debugger.IsAttached) global::System.Diagnostics.Debugger.Break();
            };
#endif

I have a feeling its something to do with InitializeComponent but im not sure. Here are the errors

}

for now its just the default. some times when i create the project again with complete defaults it does the same thing. its like its random I also get this error after stopping the Debug session in the Debug Console which could be related? Exception thrown: 'System.Runtime.InteropServices.COMException' in WinRT.Runtime.dll WinRT information: The application called an interface that was marshalled for a different thread. but doesnt show for e as a stack trace i have no warnings or errors in either code

* close VS * remove the hidden folder .vs * remove all bin and obj folder next to each csproj (DO NOT TOUCH THE .git FOLDER OR WHAT'S INSIDE) * restart vs

that still didnt work. this is the stack frame for it

UTD.WindowsGUI.dll!UTD.WindowsGUI.App.InitializeComponent.AnonymousMethod__4_2(object sender, Microsoft.UI.Xaml.UnhandledExceptionEventArgs e) Line 69 C#

and i added a textblock to the stack panel too dont worry about this anymore, turns out Microsoft.UI.Xaml NuGet package was causing all of the issues
