Steps to reproduce the issue

Forum users are reporting Issue After Updating to Joomla 4.4.0: "UserFactory not set" Error in ActionlogModel. See https://forum.joomla.org/viewtopic.php?p=3707474&sid=52962b8597e3e7dd5a757ea2034c440f#p3707474

This looks like a backward compatibility break when a third party extension triggers the Action Log plugin. It would be good to have some sort of fix or an explanation.
