I started working with Scratch 3, I created several files(.sb3 files) and saved them on my (drive )computer and when I tried to open them again,Scratch 3 could not open them.
why?
Any answer will be welcome

Does an error message pop up? What happens when you try to open one?

The Scratch 3 does not respond at all when I try to open the file

And I got no error

Just to be sure. To open the files, you go to the File menu and click “Load from computer”, right?

The same thing happens to me and it turns white
