ModuleNotFoundError: No module named '_ctypes' on Python 3.10.4

[adderall-prozac]

I installed via pip on my new machine (Fedora 36) but whenever I tried to run the command it did not work

Traceback (most recent call last):

I've tried running

sudo dnf install libffi-devel

but the error persists.

Which python version are you running (your title says 3.10 and your logs 3.8)? Which command did you type to install md2pdf?
