Corrupted sketchup file will not open

I saved my sketchup file last week and today it wont open, It says the file is corrupted an I´m not really sure what to do. Could anyone please help?

Where did you save the file? Have you looked there for the .skb backup copy? Did you try renaming it to .skp and opening it? Your profile says you are using SketchUp 2026. Were you also saving a copy to Trimble Connect?

By the way, there is no Classic license for SketchUp 2026.

I was saving it to my desktop and to work drive. I tried renaming the .skb file to .skp but it did not work. I did not save to Trimble Connect.

I couldn’t do anything with it but maybe @colin would have luck.
