Recently upgraded from Pro 2.7.2 to Pro 2.8.1.
After cloning my environment and installing the untools 2.8.1 I get the error the attached error. This error also arises with the latest release of dltsolutions.
I've tried the following via the Python Command Prompt.
-Creating a new conda env. in a new location to ensure the initial install was correct.
-Removed 2.8.1 and installed 2.7.0
Also, according to this article my proenv may be messed up however I don't see this file in the location the article suggests.
