I'm a member of 102 groups on Meetup. Not sports, because I have never played any sport, but many tech groups, reading groups, and hiking groups. No singles groups, because I'm not looking to date and I'm not in my 20s anymore (and don't feel like paying membership fees).

I have been methodically taking turns trying all of their in-person events.

Hiking groups are dominated by retirees who have trouble relating to me socially. I have not found a reading club that meets IRL. The "philosophy meetup" is a bunch of 25-year-old crypto bro edgelords. I keep going to tech meetups, some for over a year, but everyone at them either goes with coworkers or is really apathetic and alienated.
