Could you get an MSBuild binlog and attach it here? Thanks!

msbuild.binlog.zip

Let me know if this doesn't work

Unfortunately that didn't give me many clues.

Is there any chance we could get access to your project to compile it ourselves?

@rolfbjarne I created a respository and gave you access. WasatchBackcountryAlliance is the app to build.

I ask that you destroy the source code after you've diagnosed the issue.

I confirm I can reproduce the problem; I'll see if I can figure out where to route the bug and create a smaller test project that doesn't involve any of your code.

Well this error occured in my project as well, I went with:

<PropertyGroup Condition="'$(Configuration)|$(TargetFramework)|$(Platform)'=='Release|net9.0-ios|AnyCPU'">
    <EnableSGenConc>True</EnableSGenConc>
    <MtouchInterpreter>-all,System.Private.Windows.Core</MtouchInterpreter>
</PropertyGroup>
