> Interesting. Because both errors/conditions are mapped to ERROR_INVALID_HANDLE we need the creation time. I can work on a patch for that.

I don't understand why any patch for CPython is needed at all. Using invalid handles is a serious programming bug (it's similar to using freed memory), so CPython doesn't really have to attempt to detect the programmer's error, at least not if this attempt significantly complicates  the existing code.

In my opinion, the CI failure linked in the first comment simply indicates a bug in psutil and is unrelated to CPython at all.
