Workload installation failed: Workload ID android isn't supported on this platform.

**Background:**
I try to get the Uno framework installed on a Windows PC, but the install fails on installing dotnet multiple workloads, amongst which Android :

```
C:\....\>dotnet workload install android
Workload installation failed: Workload ID android isn't supported on this platform.
```

This seems to be because the Workload is not recognized; In fact, the installable Workloads list is very empty, and has a lot less entries than I have seen in examples:
```
C:\...>dotnet workload search

Workload ID Description
--------------------------------------------------------------------
macos .NET SDK Workload for building macOS applications.
maui-tizen .NET MAUI SDK for Tizen
maui-windows .NET MAUI SDK for Windows
```

Even though the manifests do seem to exist
```
C:...>dotnet workload update --ignore-failed-sources

Updated advertising manifest microsoft.net.sdk.tvos.

```

I am running Windows 22H2 19045.4651, VS 17.11.1, and Dotnet 8.0.3 (apparently with maui-windows workload installed):

I tried
- Removing any except for "https://api.nuget.org/v3/index.json" from the Nuget URL.
- Updated Visual Studio, made sure that .Net Multi-platform App UI development and Mobile development with C++ is installed as well
- Removed other Visual Studio older installations
- Performed a full .Net SDK and VS uninstall and subsequent reinstall

### Additional info

Use `dotnet workload search` to find additional workloads to install.
