High CPU usage - possibly cron service

Plex Media Server Desktops & Laptops
1

Ubuntu 20.04.6 LTS
Server Version#: 4.100.1

I have recently noticed my PMS is constantly using 50% of my CPU.
I examined running processes, an dfound all of this CPU power is taken by one process:

Process name: python
User: plex(1001)
Control Group /system.slice/cron.service(,blkio, cpu, cpuacct, devices, memory, pids, systemd)

also my system log has a lot of session opened/session closed messages repeating every minute. It looks like this:

pam_unix(cron:session): session closed for user plex
(plex) CMD (/home/plex/.cache/.python/python)
pam_unix(cron:session): session opened for user plex by (uid=0)

I have downloaded the logs:

I am not sure how to approach this problem other than attempt to reinstall PMS, any suggestions would be really appreciated. Thank you.
