command line – Ubuntu 20.04lts, cron -l fails Resource temporarily unavailable

I’m getting this:
Cron won’t list current jobs, ie sudo cron -l fails. It returns:

can't lock /var/run/crond.pid, otherpid may be 468110: Resource temporarily unavailable

I’ve tried the following steps:

sudo kill -9 $(cat /var/run/crond.pid)
$ ps aux | grep $(cat /var/run/crond.pid)
root        1322  0.0  0.0   9412  3096 ?        Ss   Feb15   0:00 /usr/sbin/cron -f
$ sudo service cron stop
$ sudo service cron start
$ sudo cron -l
cron: can't lock /var/run/crond.pid, otherpid may be 468110: Resource temporarily unavailable

The status of cron:

sudo service cron status
● cron.service - Regular background program processing daemon
     Loaded: loaded (/lib/systemd/system/cron.service; enabled; vendor preset: enabled)

       Docs: man:cron(8)
   Main PID: 467956 (cron)
      Tasks: 1 (limit: 38312)
     Memory: 484.0K
     CGroup: /system.slice/cron.service
             └─467956 /usr/sbin/cron -f

The task gets locked immediately with a new PID, so something is grabbing it right away.
I also haven’t actually added any cron tasks myself, however I do have clamav installed and it has a freshclam task associated with it.
Any ideas?
