IMac continually reboots in Sleep mode after Sonoma

Hi all-

Since installing Sonoma in the past week or so, my iMac reboots every day, at least 1x per day. I just noticed it happen when I walked away after about an hour of inactivity.


An earlier post about this issue suggested that under Privacy & Security, a setting might have been activated to log off after a period of inactivity. I confirmed that this option is not on. Which makes sense because there's an error pop-up each time it restarts.


Following the suggestion of another user, I pasted that message into EtreCheck and I have the output. Is that something I could/should post here? It's pretty long. If it helps, here's the Diagnostics portion of the report.


Any feedback or suggestions would be much appreciated. Thanks!

Sleep is unnecessary and should be disabled. Shut for long absences/idle overnights (i.e. do not manual-sleep), and for regular operation, use the settings exactly as shown here Wake up a remote Mac mini - Apple Community, should fix.
