Hi,
I just got some response on this through conda-forge community, that this
would be due that the DLL resolution order was changed in 3.8 (but
temporary reverted in conda-forge python).
https://github.com/conda-forge/python-feedstock/issues/552
I will try to test this, if correct it will need to also go into the
generation of wrapper code I would assume.
Best Regards
