Damaged Civil 3D File

I opened the file, I found it damaged and can't rebuild corridor, can't extract solids all drawing style had changed, and if I try to make one of the previous orders it closes and makes recovery have same issues and tell the attached message.

Try inserting it into a blank drawing and see if that helps.  If not, LANDXML the corridor out to a clean drawing and work on it there.  Sorry, I'm afraid I can't look at the drawing right now.

To add to what @brian.strandberg said. Insert it into a new (blank) drawing created from the Template that would have the correct styles and settings.

Hi,

It opens without any error in Civil 3D 2025.

The major issue is all the civil 3D objects (Alignment, corridors etc) are turned off.

 Civil 3D will only act dynamically when the layers are on or freezed.

So I suggest you to open the drawing and turn on all the layers that are turned off.

Then see if the drawing works.
