Unexpected File Format When Open in SU 2023

Hi, when I open my model in Sketchup2023 pro, this info pops out, appreciate if someone could help to fix it. It is critical to the work I’m working on now.

The file could be downloaded in here:

Where have you been saving the file as you were working on it? Can you share the .skb file, too?

Actually, update to the latest version of SketchUp 2023 and you’ll be able to open the file.

Here’s the recovered file. I also purged unused stuff from the file. Lots of bloat.

Well received, thank you!
I was also try to find the skb file, but could not find it anywhere in my computer.

Update to the last release of 2023 or upgrade to 2024.
