#help DLL load failed while importing ogrext #help


Please help a novice troubleshoot my import of the package into an environment that's summarized below.
OS: Windows 10
Conda 4.11.0
Python: 3.8.12
Jupyter: 6.4.8
fiona: 1.8.13.post1
geopandas: 0.10.2
GDAL: 3.0.2
pip: 22.0.3

When I import fiona, why does Jupyter return the error below?

     82     os.environ["PATH"] = os.environ["PATH"] + ";" + libdir
