Bug description:

I built python 3.13.1 from source using MSVC , using call build.bat -e -v -p x64 , had no issues in building . After building it I installed numpy 2.1.0 whl from pypi. then I tried using this python over nfs on remote host I am getting numpy import error -

ImportError: DLL load failed while importing _multiarray_umath: The parameter is incorrect.

same set of steps works for me with python3.12.6. seems something is changed in 3.13.1 when trying import over nfs.
could someone please help As I am unable to figure out.

raised issue with numpy dev as well https://github.com/numpy/numpy/issues/28216 , but it seems issue with the way how new python is working. any help is appreciated.

Research direction

Start by reviewing linked PR gh-129616, then reproduce the failure using build.bat, Python 3.13.1, numpy 2.1.0, and an NFS-hosted Windows environment. Done means numpy imports successfully over NFS on Python 3.13.1 while the existing local-import behavior remains intact.
