I don't have that kind of gathering on side. There are no programming meetups. It's an industrial area. My job mostly involves programming equipment operation using WinForm and WPF. I sometimes wish there were such meetups too. Around here, it's all factories
yeah you can just start your own! meetup (and if you have fb groups) have a good chance to bring in lots of people.
Create your own low-stakes "Beer & Programming" or whatever is doable where you live.
I grew up on a island where there was maybe one or two other people who knew computers enough to know programming as a thing existed as a concept, but similarly to you, absolutely nothing else, and it gets very lonely and outright boring after a while.
I solved this (accidentally) by moving to another area, but isn't possible for everyone, then the closest you can get to that would be to bring people closer to where you are instead, or start up something small and reoccurring :)
