Board Games!
You could try DND open play events at hobby shops.
Board games. Either just standard board games and chat while you play, or something like wavelength, that’s a question, or herd mentality to actually get to know people through the game.
I’ll second this. For some folks just hanging out with people can be exhausting if you’re not naturally chatty. Personally, I run out of meaningful things to talk about in focused conversation pretty quickly and need a chance for my brain to “reload” or I’m stuck talking about the weather to keep a conversation going. This goes double with people I don’t particularly know well.
If you’re playing a game with folks, most of the time everyone’s focus is on the game or talking about things related to the game which is easy enough to do since it is a shared experience. I often find I have a whole bandolier of semi-related ideas to discuss or funny quips that build up as we play ready to be deployed at any available opportunity. That feeling of plenty in terms of conversation makes socializing over board games so much easier for me.

Larping works great for me.
Rock climbing, go to your local climbing gym (if you have one) and take an intro class and then go hang out once you understand the basics. It’s such a welcoming community and people are really friendly and helpful towards beginners. Gyms also have new climber nights depending on the gym and those are great chances to meet people.
I second this. Bouldering especially since the climbs are quicker.
You’re on Lemmy, so I’m assuming you’re of a geeky mentality. If so, a local hackspace/hackerspace/makerspace would be a good bet.
On paper, my local one is a communal collection of tools we can all use. In practice however, it’s an excellent social group for fellow weirdos. We just also have some really fun toys to use, when we need them.

It’s not fully inclusive of all of them, but a good starting point.
