Update: I elected to re-install Monterey OS last night, only to have the automatic restart to reappear this evening when I woke my Mac from sleep. I installed and ran EtreCheck, receiving the error messages noted below. I also ran Apples Diagnostic tool which came be with no problems being found. Lastly I elected to delete Malwarebytes this evening. I'll do a full shutdown/start, and see if the problem occurs again.
