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>

Smaller test case: aot-instances-1003365.zip

To repro: unzip & run ./bug.sh

Binlog: msbuild.binlog.zip

@rolfbjarne thanks for looking into this!

Just to let you know that I have this problem also - exactly as described above. I gave the solution from @formerlymisterhenson a shot and my build has now completed OK. However, not sure whether

True
-all,System.Private.Windows.Core

is going to have any adverse effects?

@BrzVlad could you please repro from Rolf's repro and get a real callstack - the one in the crash report is probably without symbols. That should help us triage this better.

[GUELIANEBelkacem]

Any news on this issue? we have the exact same

[BrzVlad]

The fix is there, the release cycle will take a while. I would assume the new .NET9 version will be available sometime in January.

[vitek-karas]

The backport to 9 is #110271.
