Work isn't the only place you can socialise with people. You seem to have a deeper problem if you're using work to fill that void. Do you need help on finding alternative sources?
On a weekday pre covid many people would spend about half their waking hours at work so its reasonable for work to be a major social component in their lives. I'd guess that other social activities they might have been doing were also curtailed due to covid. As another single person I can definitely relate to feeling very isolated over the past year.
