I have a final update: I got my refund today! I'm sure every situation is going to be different and am not sure what is different about mine but I have it. One possible difference may be that I already and an ID.me login with the IRS. I'm not sure if that was enough to release the flag or what. I never really got an answer as to what happened; literally one day it was pending the letter and the next day it wasn't.
Good luck everyone.
