You might see if Outdoor Gear Exchange has any groups for some of those lower impact group sport activities. Group hikes and kayak rentals come to mind as possibilities!

Another thought is to check out art, craft, and/or maker spaces or music dojo if you have an urge to be creative in any way. Pottery, painting, sewing, building stuff, cooking classes, jamming with others if you play any instruments, maybe?

And then I also hear there are local DND groups, the Board Room (board game place), and Meetup.org events happening from time to time. Good luck in your search!
