.net maui publishing android app fails due to issue during linking

I have an .net maui application using .net 7 preview 2 that I want to publish for Android.

My publish command: dotnet publish ${{env.UI_PROJECT_PATH}} -f net7.0-android -c Release

This gives me this error:

C:\Program Files\dotnet\sdk\7.0.100-rc.2.22477.23\Sdks\Microsoft.NET.ILLink.Tasks\build\Microsoft.NET.ILLink.targets(86,5): error NETSDK1144: Optimizing assemblies for size failed.

I tried to include the SkiaSharp.Views.Android Dll so that is not trimmed with this:

    <PropertyGroup>        
        <EnableTrimAnalyzer>true</EnableTrimAnalyzer>
        <PublishTrimmed>true</PublishTrimmed>
        <TrimMode>partial</TrimMode>
    </PropertyGroup>

    <ItemGroup>
        <TrimmerRootAssembly Include="LiveChartsCore.SkiaSharpView.Maui" />
    </ItemGroup>

But it seems that didn't work. I could disable trimming, but then I would have to disable AOT as well which I want to avoid. enter image description here

Is there another way to circumvent this issue?

I'm not expert enough to explain the intricacies of the situation but here is a quick workaround (see comments to question above for more details).

Right click the project and select "Properties"

Find "Enable trimming" and uncheck it. enter image description here

Then find AOT and uncheck it too 2

To be clear, this may not be the best way to resolve it permanently since the app will be less optimized.
