Shelagh6 Would online courses be something that would interest you? There are a lot of such courses available on Zoom, and they cover a wide range of subjects. You don't meet people face to face, but you do meet people on screen, and can stay in touch after the course finishes, knowing in advance that you have an interest in common.
Check out WEA for starters? They usually run local courses in places like church halls and community centres, but have gone online because of Covid. When things open up again they will go back to meetings, but my guess is that they will continue over Zoom too, as their mission is to reach as many people as possible, and Zoom has opened that possibility.
CityLit is more expensive, but offers good courses too, and you could check out Eventbrite (a ticket provider) to see what else is available in your area. The Centre For Lifelong Learning, based at York University is now online, too, and they offer a range of courses at very reasonable rates.
There are others out there, but I only really know about the ones in the subject that interests me. If you search for 'online courses in XXX' you will find plenty in other areas of interest too.
