CorelDraw X8 doesn't want to open CorelDraw X8 files

After saving my file on Corel Draw x8 version, the same doesn't open later. When I try to open, the file opens blank.

I saw this:

but it doesn't work.

The file has 2 weeks of work, 15 sheets, a multitude of styles ... This is hell.

Anyone have any idea how to fix this?

Notice: I can't send the file to anyone.
