Unexpected file format not working

Hello, I’m having problem trying to open a project file. I worked on this afternoon and it work just file and saved it. but then I got the “unexpected file format” when I tried to open it again right after saved it.
I had tried every solutions, changing it for skp, restating my computer, send it to my C drive. Nothing worked.
I’m including the file in here, please help?

I wasn’t able to recover much. Look in Materials and Components, to see is recovered. There is nothing in the scene.
