Possibly related to https://github.com/dotnet/runtime/pull/108246. @eiriktsarpalis could you take a look please? The full range is https://github.com/dotnet/runtime/compare/79a71fc750652191eba18e19b3f98492e882cb5f...9d9c64dfe1c9bbc5a9324a1e6d31be8628bbf876

Unlikely to be https://github.com/dotnet/runtime/pull/108246. The changed component is not exercised by the benchmark in question.
