@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 https://github.com/dotnet/runtime/pull/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
