RUSH Unable to open project

I spent hours working on an edit only to close it down for the night and awake the next morning unable to open it. It's there. Synced to my desktop. Go to desktop, it opens but is completely blank. It has the thumbnail picture so some information I uploaded was absorbed. On the mobile app it just gives me an error message  I'd like not to start over if someone has any ideas or if TECH SUPPORT will waive their magic wand, that would be swell
