Hi, I have the same issue. Inner exception from linker is:

System.ArgumentException: Member 'System.Int32 SKCanvasView_ignorePixelScaling' is declared in another module and needs to be imported

Same but with Maui Compatibility controls library:

Fatal error in IL Linker
  Unhandled exception. Mono.Linker.LinkerFatalErrorException: ILLink: error IL1011: Failed to write 'obj\Release\net7.0-android33.0\android-arm64\linked\Microsoft.Maui.Controls.Compatibility.dll'.
   ---> System.ArgumentException: Member 'System.Int32 toolbar' is declared in another module and needs to be imported

OK, based on some further testing and checking binlogs, we have confirmed it was the new linker step that was added in GA. This was disabled for the upcoming service release in dotnet/maui#11096 as a result of dotnet/maui#11069.

The solution for now is to use this in your csproj:

<AndroidLinkResources>false</AndroidLinkResources>

The next servicing release of .NET MAUI will have this disabled already.
