Python 3.9 not supporting Windows 7 *is* the reason. python39.dll is linked against libraries which only exist on Windows >= 8.1 so it fails to load. If you want to support Windows 7 then you should be building on Windows 7 so that you aren’t picking up libraries which are similarly dependent on newer Windows libraries.
