I have switched a project (Xamarin, iOS, Android) from VS for Mac to VS Code (Mac-Version).

Wehn building I get the error: warning NU1504: Duplicate ‘PackageReference’ items found. Remove the duplicate items or use the Update functionality to ensure a consistent restore behavior. The duplicate ‘PackageReference’ items are: Microsoft.Maui.Controls 8.0.7, Microsoft.Maui.Controls 8.0.7. [TargetFramework=net8.0-android] for all TargetFrameworks.

There is no PackageReference in the project. There is only one .csProj-file, in which
net8.0-android;net8.0-ios;
is defined.

Can anybody help out of this?

I have deleted the bin- and obj-folder, restarted. Asked and followed some instructions of ChatGPT, but nothing helped.
