Project file is corrupt

Hi everyone, I am hoping someone can please help me out.
Running on windows 10
I am working on a book and have about 12 folders in the project.

Was working on the project something went wrong with another app that lead me to restarting Windows.
When it got back running, I tried to open my project and find that most of my work is gone.
When I open the project folder in a file explorer, I can see all the text files. Everything seems to be there, but the Scrivener project file does not see them.

What can I do to bring this back?
