File "/usr/local/lib/python3.8/dist-packages/gunicorn/arbiter.py

You are running the wrong instance of gunicorn. You are running a global system-installed one, but you should be running the one inside Netbox's virtualenv. The global one doesn't know about the Netbox virtualenv or the packages installed in it.

This is controlled by /etc/systemd/system/netbox.service. There's a working one you should copy in the contrib/ directory. It should have a line like this:

ExecStart=/opt/netbox/venv/bin/gunicorn --pid /var/tmp/netbox.pid --pythonpath /opt/netbox/netbox --config /opt/netbox/gunicorn.py netbox.wsgi

cd /opt/netbox
. venv/bin/activate
this resolved my issue, Thank you for your help @candlerb
