I have been working on a homework that I must deliver tomorrow, affinity publisher closed out of nowhere. (I left the publisher with the document open for at least an hour, then when I wanted to go back to work, I can't quite remember which button I pressed, but I think I clicked on the "layers" tab to duplicate a layer, it was loading and crashed. Then when I opened it it told me if I wanted to recover an unsaved file, I said yes, and then the message that the file is corrupted popped up). Now when I open the document it says that it is damaged and that it should be closed. I was about to finish, my homework is for tomorrow and I don't know what to do.
