Windows 10 / Cygwin 3.4.6

Installed python 3.9: runs fine.  Ran pip3 -V: shows version.  Ran pip3 -V again: no output.

Something seems to happen when I run pip3 for the first time that breaks subsequent invocations.  Reinstallation yields the same results.  (Reinstallation also yields the following (perhaps unrelated) error).

Error in uninstall
running: C:\cygwin64\bin\bash.exe --norc --noprofile "/etc/preremove/python39-pip.sh"
abnormal exit: exit code=2
