It will take a Snap Shot - both the hardware and software. Run the application with Full Disc Access ( Security & Privacy - Full Disc Access ). The application is free or paid from added features. Suggest downloading the Application Etrecheck directly from a well Respected ASC Contributor. IMHO - a Time Machine Backup to roll back the the computer in time may or may not solve the underlining issue If as one writes above the Terminal Command are getting Stuck - IMHO this computer is seriously compromised.

Or better yet, are there some plist file or cache that can be removed to reset this particular program (the update manager)? Is there a way to use Time machine to reset the computer to a few weeks ago, before this error happened? When trying "softwareupdate -fetch-full-installer -full-installer-version 11.6.2 ", the only output is: The terminal gets stuck in the same manner, outputting only: "Finding available software".
