Not sure if you do not have any LaunchAgents or LaunchDaemons installed that may cause a kernel panic or if the report was edited, because there are none showing there. There is nothing in the report that would point to a software issue.

All I could suggest to try is:

Update to Sonoma 14.5
Remove any external devices such as drives or monitors
Start up in Safe Mode

Start up your Mac in safe mode - Apple Support

If no luck, then the next step is to take it to Apple for diagnostics as it would most likely be a hardware issue:

Thanks for your input. I tried changing the setting and it did not change the behavior. I also set up boot camp to see if it happens while running windows. And surprisingly it was stable and does not restart. I left my iMac on booted into windows for 2 days and experienced 0 issues. When I restarted back in to Mac OS it immediately shutdown though.

I have 4 16gb sticks of ram in this iMac so I am removing 3 of them and testing it stick by stick on memory channel A to make sure it is not a ram issue. If I experience the same problems I will try try memory channel B. Any other suggestions or ideas?

Use the settings below exactly as shown, might fix (display off timer, your choice). Also, do not manual sleep, shut for long absences and overnights and let the settings take care of the rest.
