Nothing but a white screen shows up when opening the project

I was adding a bunch of new lines at once and hookpad crashed. Foolishly I pressed S on the white screen so now everytime I open the project it is nothing but a white screen. Is there any sort of old versions of the project saved anywhere? I only had one copy of it because I had never experienced anything like this before. I really need this project to be rescurrected for my music grade so any help is absolutely vital.

I know that while in hookpad, in ‘File’ at the bottom there’s a ‘Recover from backup’ option.

It should give you a list of auto saves that are taken every 30 seconds. Try going back before you got the white screen.
