This issue also appears here:

The short fix is to either
Try uninstalling “Čitač elektronske lične karte”

remove the line
if certs: self.load_verify_locations(cadata=certs) from file “C:\Users\USERNAME\AppData\Local\Continuum\anaconda3\lib\ssl.py”, lines 470 and 471

Another solution would be to replace
self.load_verify_locations(cadata=certs)
with
“”“self.load_verify_locations(cadata=certs)”“”

in:C:\Users\USERNAME\anaconda3\Lib\ssl.py

and restart anaconda navigator
