I performed the most recent Monterey update on my Mac desktop this morning and it is now continuously restarting to the progress page over and over. I have tried to access safe mode without any luck and fear this computer is now useless. What are next steps?

It is unclear what most "most recent Monterey update" you are referring to...?
point update?
macOS upgrade?
What is a progress page over and over...(?)

If necessary boot to Recovery or Internet Recovery—
Mac’s before June of 2013 do not support Internet recovery
Boot into Internet Recovery (Option Command R) and from the dropdown menu: Utilities> Disk Utility> run the First Aid on your Macintosh HD (and the "Macintosh HD-Data" volume as well if Catalina/Big Sur/Monterey) If errors are found and repaired, run again until no errors reported.
