Session creation fails with Windows Error 0xc06d007f

I'm running the nifgen_standard_function.py example and am unsure as to why it's producing this output:

File "C:\Users\att\Documents\nimi-python-master\nimi-python-master\src\nifgen\examples\nifgen_standard_function.py", line 47, in <module>
    main()

OSError: [WinError -1066598273] Windows Error 0xc06d007f

I have downloaded the NI-FGEN (version 20.0.0) driver from the National Instruments website and am using python module nifgen=1.3.2.
Any tips on how to fix the error would be appreciated!

This is tracked internally at NI by AB#1659694

Update on internal bug (AB#1659694): @dylan-matthew-turner did some good debugging and root-caused the issue.

Summary: The failure happens when any nimi-python session is opened using the Python interpreter available in the Microsoft store.

Details: Python available in the Microsoft store is an UWP app, which has stricter restrictions on loading dependent libraries. Some dependent libraries do not comply with these requirements, and hence session creation fails.

Workaround: Use Python available elsewhere like Python.org.
