Premiere randomly erased some of my project and not responding to keyboard shortcuts.

Yesterday I edited and exported a video in Premiere. Today, I went to open the project and the intro is completely gone, aswell as random parts of the audio in the beginning. I have not touched the project at all since yesterday. All files are in the same location, and have not been moved or altered. Premiere seems to load the project and files, but absolutely nothing shows up, there are no windows besides the main gray screen, I have to go in and add the windows again each time it launches. I am also not able to select different workspaces, they are all grayed out. Premiere also doesn't close when I click the X in the top right or go to File -> Exit. I am on a super tight deadline as this is an assignment for my class. Any help is greatly appreciated.

Thanks,

Ethan
