CollectionView MoveCurrentToPosition (clickedIndex) error, from Uno.Extensions.Reactive.WinUI version 3.0.10

Just like this question https://github.com/unoplatform/uno/issues/14792

It's not compilation, it's publishing Properties/PublishProfiles/win-x64.pubxml [log.zip](https://github.com/unoplatform/uno/files/14638704/log.zip) 

The default template is like this! Microsoft's support for Winui3 is still relatively poor

The official Winui3 template from Microsoft can be used for publishing, but uno's default template will fail. I can't find the reason, even without Uno Compile with Sdk sdk.

The storage issue with Application Data Key Value Storage has been occurring for a long time. The problem is this https://github.com/microsoft/WindowsAppSDK/issues/2639 You have extended [Settings](https://github.com/unoplatform/uno.extensions/blob/main/src/Uno.Extensions.Core.UI/Settings.cs) why not use it here

There is no error messages , only issues with nullable types. After modifying the nullable type, the error still exists.
