Weird issue with freshly installed environment set-up with micromamba

[Robinlovelace]

Don't think this is reproducible but reporting here in case of interest to others:

I ran the following command:

micromamba run -n geocompy quarto preview

And got this:

  Cell 13/50...Done
  Cell 14/50...Done
  Cell 15/50...

An error occurred while executing the following cell:
------------------
gpd.read_file(u, layer='Placemarks')

Confirmed: just hit the same issue on Linux (above was on Windows):

Previous commit seems to have fixed it. Closing for now.
