Homework file just vanished

Hello I was using a ui kit to finish my design homework and when I opened Figma back up the file just vanished as I was working on it. It’s not in my drafts and it isn’t anywhere to be found. This was my homework and it’s due at 11:59 tonight. Hoping someone can help me retrieve it asap because now I don’t have the time to finish all of the screens in enough time. Thanks!
