Windows 10 laptop.
Python 3.13.5 x64 is installed and pip successfully installs pywin32 311. The installed _win32sysloader.pyd matches the file extracted directly from the downloaded wheel by SHA256 hash.

However, Python fails to import the native extension with:
ImportError: dynamic module does not define module export function (PyInit__win32sysloader)

This prevents pywin32 from loading.

Ideas? what do to next to further diagnose/resolve?
