Hi, I have an old XF project that I decided to upgrade to Maui. I downloaded Upgrade Assistant and when I run it is finished but with an error. As suggested my project uses Xamarin.Forms 5.0 and .NET Standard 2.1 and it runs correctly. This error happens regardless of the type of upgrade (in-place or side-by-side). The error: happens on a stage "Microsoft.NETCore.universalWindowsPlatform 6.2.12" with a description "Could not find 'Microsoft.WindowsAppSDK/' on the configured NuGet feeds" EDIT: added screenshotMAUI upgrade error.jpg
