My clock, bluetooth, wi-fi and other controls disappeared from the menu bar following Monterey update

I figured out what was causing it. I had been running flux, a third party extension that controls the display color profile depending on the time of day, similar to night shift. Over the past year or so, I had been getting a warning when applying updates. It said that my system was using a component that may not be compatible with a future system update. Well, apparently that day has come. Remembering that warning, I removed 'flux' from my system and rebooted. The problem went away and all the controls now show up in the menu bar. I now use night shift instead. It is more or less equivalent and will not give me any issues, so I am happy with this solution.
