Can't update to latest release ("No module named pip")

[smurfxx]

I'm trying to update your plugin to version 4.2.0 but the installation fails.

Looking the log file I see this error:
2023-08-28 08:38:03,227 /home/pi/OctoPrint/venv/bin/python3 -m pip --disable-pip-version-check install https://github.com/derekantrican/OctoPrint-Webhooks/archive/4.2.0.zip --no-cache-dir 2023-08-28 08:38:03,829 ! /home/pi/OctoPrint/venv/bin/python3: No module named pip
I checked my pip version and it seems everything ok:
pip --version pip 20.3.4 from /usr/lib/python3/dist-packages/pip (python 3.9)
How can I solve this issue?
Thanks!

I would suggest posting about this on the octoprint forums (https://community.octoprint.org) and see if they have any suggestions. Post a link to your post here and I'll follow it and see if anything needs to be updated in regards to the plugin here
