Cannot import Altair SLC dataset file (tried Python 3.9-3.12, NumPy/Pandas combos, Anaconda)

I've tried multiple Python versions, NumPy, Pandas, with and without Anaconda envs,
but cannot import an Altair SLC dataset file (e.g., data.slc) without import errors or crashes.

Works!!!

Altair SLC

With these versions.

Working on a way to use python 3.9 for import and export and Python 3.13 for everything else.

Too many packages lack support withg 3.9?
