            Seems that this is a known Conda issue (#1, #2, etc).

            Adjusted by running:

            $ conda install --no-update-deps tornado=4.5.3
            

            Unfortunately, this pulls the shared stack out of sync with the lsstsw environment, but I think we have to live with that for now.

            Yusra AlSayyad, can you confirm if this fixes the problem for you?
