Hello, so i’m having the “unexpected file format in sketchup 2026 pro.

I’m a bit worried i’m not able to retrive the file and its a very important i do. anyone can help?
i’ve reinstalled sketchuo 2026 from the official website. I’ve tried renaming the backup and i still cant open. I think i’ve done all the suggestions i’ve seen around here at similar topics. My hope is that saviour @Colin can help. I’ve seen some you were able to retrive some corrupted files.

Thanks
