Cannot export connections / servers - pgAdmin4 4.24 (windows)

Hello -
I'm attempting to "dump servers" according to documentation at
https://www.pgadmin.org/docs/pgadmin4/4.24/import_export_servers.html... I tried searching your archives for
dump-serversbut got "no hits". Seems unlikely, maybe something screwy with the search but there is no help anywhere
thatI can find. 

It fails with an error " ModuleNotFoundError: No module named 'encodings'".  Any ideas what I am doing wrong? I did try
settingthe env variables PYTHONHOME and PYTHONPATH to several different things in the "\Program Files\pgAdmin 4\v4"
treebut not sure what it wants, if that even matters.  I do see the servers in the Web app. 

This is the pgAdmin4 v 4.24 Windows 64-bit version on Windows 10 added via the installer. I am not sure if I am running
in"server or desktop mode" but probably desktop?
