I have problem while saving file

No recovery for that file. It’s nearly half filled with zeroes.

Your profile says you have SketchUp 2024 but this file was last saved in SketchUp 2023. Looks like a cr acked version. Is that correct?

It my mate file and I use license Sketchup i can prove

and this file can fix or not ?

No it can’t be fixed.

If you have a current subscription you should update to the current version of SketchUp and you should be saving backups of your files to Trimble Connect.
