I often have to go to editing photos in CorelDraw.

By the nature of my work, I often have to go to editing photos in CorelDraw. But now I thought a lot about the problem with opening a file with a processed photo. Something in it, apparently, went wrong with the last salvation, and now I see something incomprehensible, and not what I saved the last time. I don't know what happened to the file, but I urgently need to return everything to its original position. How to do it?
