Could it be introduced by https://github.com/dotnet/runtime/pull/103777 @steveisok or does the change only affected NAOT?

It only impacted nativeaot. It was really specific. If you had the mono library builder workload installed and you tried to build a static/shared library with nativeaot, you couldn't.
