When faced with this type of problem I introspect from the Python REPL prompt.

Run python 3.9 and see if os.pidfd_open is defined?

Do not do this inside PyCharm to rule out a problem with PyCharm.

Also you will need to be running a linux kernel + glibc version that is new enough to proved this to python.

This is what I see with Fedora 36:

$ python3.9
Python 3.9.13 (main, Jun  9 2022, 00:00:00)
[GCC 12.1.1 20220507 (Red Hat 12.1.1-1)] on linux
Type "help", "copyright", "credits" or "license" for more information.
:>>> import os
:>>> os.pidfd_open
<built-in function pidfd_open>
:>>>
