Cannot Start Maui Tutorial on Windows

[markgr]

Ok so this is really weird

So Env: - Visual Studio 17.8.3 Dotnet SDKS: 8.0.100 All workloads up to date

I download the whole Git repo - I then open the DotNet MAUI tutorial project maui-samples\8.0\Tutorials\CreateNetMauiApp - Step 1

Build for windows - I get the following exception

If I try it from a command line

Unhandled exception. System.TypeInitializationException: The type initializer for '<Module>' threw an exception.
 ---> System.TypeInitializationException: The type initializer for 'WinRT.ActivationFactory`1' threw an exception.
 ---> System.Runtime.InteropServices.COMException (0x80040154): Class not registered (0x80040154 (REGDB_E_CLASSNOTREG))

However - if I create a brand new MAUI project in VS and attempt to run it on Windows - it works just fine.....

Any ideas of what to look for?

I should note that it all works on Android on my machine

I'm quite willing to accept that it's my machine somehow - but nothing obvious in Event Viewer etc - the one thing that I might have done was install DotNet 8.0 outside of VS - but even if I do the whole build through the Terminal only I still get the same result....

If I try from command line
