I've joined local groups for anime and videogames, but they are mostly anime. Videogames and programming seems to be almost exclusively masculine (the stereotypes are there for a reason) but the few girls there doesn't seem much different.
Maybe I've had bad luck, maybe I need to search more, but still...the situation seems to be similar everywhere.
try group that are tied to your geography rather than international subculture
eg videogaming subculture was good during 00s LAN era because it was local. you would be seeing people from your town and surrounds. now gaming is just online random anons
pottery classes, painting, hiking trails, wine bars, farmers markets .
