@JulieLeeMSFT, please update the Known Issue Error Message section with "ErrorMessage": "type is HFA but READYTORUN_LAYOUT_HFA flag is not set" so it can find the matches.

Looks like it's only failing on win-arm64 in R2R pipelines. Unfortunately, it fails only in run-time so I need to find a win-arm64 machine to repro.. but looks like it was introduced it #104411

I guess it's not a critical bug since normally it's not possible to define enums with float/double backing types, it's only possible in raw IL.

[am11]

Maybe we can disable the test on win-arm64 against this issue?

[EgorBo]

Yeah, let me disable it for now until I have a moment to fix it

#105089

@EgorBo this is also hitting on the outerloop on linux-arm64 R2R runs.

Also failed on osx-arm64 in runtime-coreclr crossgen2 outerloop https://helixre107v0xdeko0k025g8.blob.core.windows.net/dotnet-runtime-refs-heads-main-5cccc2a29c024306bb/JIT.opt/1/console.1d4c7083.log?helixlogtype=result
