Hi,
Installed Pro 2.8.1 on a clean machine (so, no upgrade). I cloned the Python Env, and closed Pro.
Installed the untools via Python command: conda install -c esri untools
When starting a new Pro project, I get this error:

after click OK, no geoprocessing toolboxes appear anymore.
Anybody got the same issue and knows how to resolve this?
Thanks,
Jan
