python-pip is broken after updates

[znavko]

Hello! I am using free vpn by protonvpn on GuixOS.
protonvpn installs own client written on python3 requiring pip3.
It works fine after installation under root.

But updates break it.

After I made under root

# guix pull && guix package -u
# guix system reconfigure /etc/config.scm
# guix system delete-generations 1d
# guix package --delete-generations=1d
# guix gc

(I have tiny ssd and need to remove generations
Also I had troubles with locale and need to reconfigure after update)

This breaks work of pip3.
Running of protonvpn is breaking cause it does not find
some packages or python3 component.

Also I cannot reinstall protonvpn cause it does not find
python3 module.

Only installing python-pip package again and installing of protonvpn
again saves the situation.

Could you check it and make some advices?
