Can’t Accept Team Project

My coworker started a team project that he worked on for his final week that I was meant to continue when he left. Today I went to accept and open the project, but when I'm in the invites tab of the manage team projects window, it won't load anything. I click accept, it loads for a second, and then appears back in the invites list. I've accepted it from my creative cloud notifications as well, but it won't let me in. Since he is gone there isn't a way to resend the invite so anyone have ideas?
