Django Apache server error. no module named 'psycopg2._psycopg' [Dulicate, but duplicate answers didn't work :(]

Question

I am running ubuntu-server 20 and I am trying to run django deplyments server on it with apache2 and libapache2-mod-wsgi-py3. I was having many errors but i somehow managed to fix them but I am stuck on this error:

django.core.exceptions.ImproperlyConfigured: Error loading psycopg2 module: No module named 'psycopg2._psycopg'

psycopg2 and psycopg2-binary are installed in my env. Also I am using python version 3.9.

Here are my apache server configs (if you need them)
