How to make more friends in university?

Hi,
So I am a freshman in university. And I have social anxiety, like I can’t carry a conversation with people whom I don’t like click with. So we were roaming around campus and we got pulled into a dorm and there was this group. The group had people I wanted to be friends with but I can’t cuz they always seemed to hangout together or seem uninterested in me. I don’t know what to do cuz recently my friends have stopped or rarely hangout with me and I don’t know how to talk to the popular people. Can anyone help?
