Starting to panic after not being able to find a summer internship

Junior undergrad from the University of Florida here. Transferred to UF my sophomore year, started off well, got lucky and found an internship in venture capital my sophomore summer that became a part-time job as an analyst that I still currently do. My boss has told me he most likely won't be able to offer me a full-time job so I've spent the past few months trying to land an internship somewhere in the corporate finance world. Problem is, I struggled when I first arrived at UF and ended up tanking my GPA from a 3.9 to a 3.3, and can't seem to get to the interview stage for any internship I apply to. My guess is I'm being filtered out at the first stage due to my low GPA. I've applied to well over 100 positions through LinkedIn job searching but haven't had any luck. While I am very happy for them, it's disheartening to see all my peers land great internships at top companies while I can't even get a call back. Not sure how to proceed from here, just looking to see if anyone has any advice on what I can do to figure something out for this summer.
