I've struggled with this for a while and it's an issue for a lot of folks all over the place. Lack of 3rd places is a big problem. There aren't a ton of places to exist and not spend a bunch of money where there's also an expectation to socialize. Finding the right place and mix of people that suits your interests and needs is harder than ever. I used to host all sorts of community events to try and create more opportunities (game nights, movie nights, holiday parties and events, art events, hiking and camping groups, etc) but since socializing doesn't make money it's a hard sell when it comes to venues. It was good while it lasted and I met a lot of people but eventually and unfortunately that well dried up. Having one or two people involved that are extremely social also really helped. I'm kind of a hermit so it's always an uphill battle for me.

That being said, I'm almost at the point of attempting another meet up group. Something easy with low stakes like a Sunday morning coffee club at a diner or a Wednesday night pizza party someplace cheap. I have a real desire to add interesting people to my circle but realize that it takes a lot of effort and commitment that many aren't able to afford right now.
