Cannot import geopandas even though it is installed in environment - python-3.x

Question

In have this behavior that I cannot really understand. Some background might be in place. I earlier created an environment called geo in which I installed geopandas. I worked like a charm, but I later realized that I wanted to split POLYGON-type objects into smaller ones.
Reading a little, I found out that QGIS has something that might help. So, following this really helpful answer (https://stackoverflow.com/a/67447061/5363686), I created a conda-qgis environment to be able to
from qgis.core import *
and it worked like a charm. I also install geopandas in that environment, as can be seen below it is there:

This, is rather strange. And yes, I open my notebook in the right environement.
Does anyone spot my mistake?
Thankful for any help!
