I had been working on a scene for hours when mysteriously my computer completely crashes and needs to restart I remember having saved several times when working so I wasn't scared. As I thought I had lost only maybe just 1-5min of work, I re-open Unity and to my surprise, my scene seemed to have reverted to one of my first saves, and because I had re-opened the scene, the Temp/_BackupScenes folder was erased...
So I was wondering, is there any way to recover Unity Scenes that does not imply the _BackupScenes folder? I don't think there is, but just to be sure because I very much remember saving the scene before it crashes...
Thank you in advance,

These should give you all the info you need. I highly advise you to back up an export on a USB drive.
