it says this does not appear to be a sketchup model. Thank you!

Your file is practically totally empty, only zeroes. Nothing can be recovered from it. Do you have the backup (SKB) file?

it has the same file size

Share it anyway. It might be viable.

BTW, if you have a .skb backup file you are not using SketchUp for Schools which is the web based version for school children. You must be using SketchUp Pro. Please update your profile.
