Many times, I get the message "Tool has failed to open" when trying one of the Utility Network Package Tools.
Only solution is to restart Pro, and mostly this solves the issue.
I already removed my Python environment, then clone the default and add the untools again. But this doesn't seems to help. I still get this behavior.
This was something I never had with Pro2.5, but occurs now with Pro 2.6
Anybody has the same issue and now how to solve?
