Hello Zachary
Time has passed, conda became irrelevant for my needs, and I am struggling to remember what technical support suggested.
The last thing we tried was to turn off the anti-virus, and I believe that worked.
Conda was still not blindingly fast but acceptable. But turning antivirus
off is clearly not an acceptable solution. I believe that the upshot was
that a fix was needed to ESRI software and would be incorporated into
a new release. Whether that happened I don't know, and I have not
not tested since.
It so happens that I am working with these python environments again
and may soon revisit. I will let you know of any new result I have when I next test
I am currently on the most up-to-date release of AcrGIS Pro (3.1.3)
