Look up local D&D groups (there's a reason it's only gotten more popular, also fun as hell with adequately decent people), or some kind of other hobby/activity group that provides the necessary pretext for complete strangers to meet without it being "weird". You can look up lists of hobbies, and just see if there's some group around. Dance lessons, communal gardening, gym/"rock" climbing (specifically, joining an “accountability group”), and even some intermittent volunteer activities (thought you want to be cautious of that one, as you are there for meeting people, not for something to do or be feel guilted into long term) are also some other things that are a possibility.
