About an exception during running the example for WinUI 3.0 demo.

I had downloaded the example, "Build2020Demo", for WinUI 3.0 demo. at "https://github.com/microsoft/WinUI-3-Demos".

The example was built with the option "x64" in Visual Studio 2019 Community and successfully done.

But, when I run the built example, I got "Unhandled exception" as can be seen in the attached image.

I have run the example in Visual Studio with "Start New Instance".

Is this exception because some components are missed?

    You must click on "Start New Instance". on the Package
    otherwise it fails at RoGetActivationFactory with REGDB_E_CLASSNOTREG
    I compiled it as x86 :
