How do I build a proper social circle post college especially in a pandemic that shut down many places in my area?

I’m rotate between some friend groups but most of them are cliques, not allowing outsiders in. I don’t know how to meet and talk to women (or people in general), beyond superficial relationships in class. The friend groups I did join were by chance, and they adopted me into it. Now after college, most of them moved away or are too busy to see me
