Saved Project, Restarted Computer, Project Didn't Open Back Up. Need Help


So I need to restart my MacBook air, and I save my project on a pin tab and restart the computer. I come back up, refresh the pin tab, it asks me: “There is a saved project, do you want to re-open it?” I click yes, and my project doesn’t come back up. If there is any way to find a lost project please tell me how.
