Since this is a tech forum, the best solutions I've seen to this problem seem to be arising on instagram due to its good location based advertising (it was originally meetup.com but they sacrificed their lead during grandstand on covid). Lots of run clubs, events, dances, and things to do get recommended in my feed all the time, and once you get into a scene people are usually recommending more things to do. There are sometimes community based apps as well which recommend local things to do. Ultimately though you need to go outside and meet people, you can't solve it by sitting in your house alone talking to internet people.
