Unexpected File Format - Help Please! recover please

hi there, my files cant be open, it come out this unexpected file format. i did change name from skb to skp, but it doesnt work on me. so anyone can recover my file ?

The file seems to be missing some important data. Can you think of anything in particular you did right before the file no longer worked?

Also, check this folder to see if there is a copy of the file there:

%LocalAppData%\SketchUp\SketchUp 2021\SketchUp\working\SKETCHUP\RecoveredFiles

Can you upload the .skb file as well?

One of the developers did manage to get the file open. Some materials may come out looking wrong, you’ll have to remake those.

One thing that showed up is that you may be working off files that are on a server. If you are, it may be better to only work on local files, and then copy those to a server if you need to download the file on another machine.

Anyway, here is the recovered file:
