Regular Restart of Mac Since Upgrading to Catalina

Since upgrading to Catalina I constantly get the following report after a restart of the machine. The restart can occur at any time, often overnight. Any thoughts on what this could be all of a sudden? I am on 10.15.7.

After reading some other threads I change the Energy Saver to Never go to sleep, but clearly that hasn't worked - latest report header below:
