WinUI 3 on Windows 11 - Unable to find package Microsoft.Windows.SDK.BuildTools - visual-studio-2022

Question

Setup:
OS Windows 11
Visual Studio 2022 community version 17.4.5
Workload installed: .Net Desktop development, Universal Windows Platform development.
Installation details:
.Net desktop development tools. Windows 11 SDK (10.0.22621.0)
I created a new project: Blank App, Packaged with Windows Application Packaging Project (WinUI 3 in Desktop)
Error list starts with
Unable to find package Microsoft.Windows.SDK.BuildTools. No packages exist with this id in source(s): Microsoft Visual Studio Offline Packages, Package source App3 C:\Users\Moshe\source\repos\App3\App3\App3.csproj
Same for all other packages.
Errors in the code The Type 'Window was not found'
NuGet settings: Package Source C:\Program Files (x86)\Microsoft Visual Studio\Shared\NuGetPackages\microsoft.windows.sdk.buildtools
When opening this folder, it has a folder "10.0.22621.1" and in it under bin, are the packages reported missing.
Here is the .proj references

What I tried so far:
Uninstall and reinstall Visual Studio.
Change SDK from Windows 11 to Windows 10 in Installer.
Use the other possible template under WinUI 3
Nothing helped.
Any pointers on how to resolve this
Thanks

Assuming that you mean Visual Studio 2022, not 2012, here is where you can find the requirements. The list below is a short version of the link. Run the Visual Studio Installer and make sure you have these items selected.
Workloads tab:
Select .NET Desktop Development.
Then, in the Installation details pane on the right, select Windows App SDK C# Templates for C# development.
If you also need C++, select Windows App SDK C++ Templates.
Individual components tab:
Scroll all the way down to SDKs, libraries, and frameworks section and select Windows 10 SDK (10.0.19041.0).
