1. Become friends with your roommate, and dorm people. You see these people everyday. Say hi to them, and just small talk for only 2-3mins time to time when people are not in a rush.
2. Play sports... (recreational/intramural), coed better.
3. Join a gym, and start exercising/living healthy
4. Make sure your hygiene is on point and dress well/better than the average. Also pay attention to your grooming and other habits (eg. eating habits). Perhaps there is something that is turning off people.
5. Try to invite people to events/things. Event just lunch at the school cafeteria. Try to form a habit to have lunch with the same people/group and eventually people will invite you to things.
Some of the folks that I went in college that had trouble making friends, apart being socially akward, had some kind of basic hygiene/grooming problem. You are not going to get invites to parties if you look like crap, and have body odor. Nobody will tell you why.
Make sure these basic stuff are covered, then the other thing is just talking regularly to the same people, having lunch with them regularly, etc...
Also, don't beat yourself up, as many people are in the same boat as you. This year is kind of unusual, as covid is still a concern and most people will be more reserved as usual.
Good luck,
