ArcGIS Pro 2.5 conda distribution issue

[RVG296]

As per the documentation, conda comes pre-installed with ArcGIS Pro 2.xx version. But, after upgrading to ArcGIS Pro 2.5, I am not able to view my conda package list or install libraries using conda. I have added conda path to my environment variables. I get an error saying 'menuinst' distribution not found. If I try to install menuinst using pip, it doesn't work either and provides the same error "No matching distribution found for menuinst".

Any help on this would be appreciated. Thank you.

Not sure if the issue is regarding upgrade to 2.5 or any python dependency issue.
