Sketchup model disappear

my old sketchup file is not appear to sketchup 2020
can someone help me ?
plz

Maybe you are trying to open the backup file witch has the extension .skb.
Try to find the file that’s ending with .skp!
Or rename the backup file to .skp…

Edit: please update your profile, SketchUp is not An operating system and your graphic card has a name and type…

Oh, and by the way, you should have posted in the Pro section, not SketchUp for web…

If you’d upload the .skp file we might be able to help you.
