Project not loading, showing gray screen

I was recently editing a project and after exiting the application and reopening it, I clicked on the project only to be met with a gray screen where the video/editing panels should be. file/edit/sequence/view/help was still there, but there were very limited options when I clicked on them. Also, all of my other projects load fine, this is the only one that won't load for whatever reason. I have tried logging out of adobe and logging in, restarting my computer and the application, and turning the cloud sync off and on again. Nothing has worked. I'm also getting a file sync error because I've hit 100GB of cloud storage, but I'm pretty sure that's been there for awhile, I just thought I'd add that bit of info in case it's relevant.
