This is likely also a user-facing issue if anyone is trying to benchmark Mono 8.0 on desktop and they have newer tfms in their project. If we keep <UseMonoRuntime>true</UseMonoRuntime> in the csproj, and remove it from the command-line args, does that fix the issue? Or do we need a more targeted Condition besides just the tfm?

Is dotnet/performance benchmarks works on BenchmarkDotNet v0.15.8 on net10.0 tfm and crashed when using nightly build?

It looks like Microsoft.NETCore.App.Host.linux-s390x nuget package seems needed to execute on s390x architecture. Thought it works without this package?
