Im being hated by this group of friends

I know this is prolly not the right forum but I don't have the energy to care about it. Im F19 I used to be super popular (due to my academic achievements) I'm not the type to boast or bully. Im a very happy go lucky person and all I do is joke around. I don't have secrets about or against me either.

Outside of my college, I have a lot of friends who appreciate me and think I'm funny. I seem to be the opposite in my college group right now. I have never felt this rejected and left out. For some reason beyond my understanding - I'm being deliberately ignored by this group of girls (two in my class a few in the other) Out of this group 2-3 of them knew eachother prior to this institution and remained friends. And quite honestly i would never speak of anyone in a high manners they're not exceptional people or the type you would miss hanging out with but yk in college u need a group to survive regardless right? I also wouldn't say they are particularly close to eachother except the 2-3 who've studied together before.

It's not even clear signs of leaving me out it's those petty middle school moves where you whisper stuff to others and talking to everyone and greeting everyone except that one girl (which happens to be me)

Now i know the obvious solution is to make other friends which I do in college - however this particular group is in my class same course so we share a lot more in terms of class hours, exams etc which makes this hard to ignore or leave. Im genuinely typing this in my college's washroom so that should tell you a lot about how i would rather stay here than amidst that group.

Do you have any solutions for me?
