It seems that there is a bug in the latest Mac version (3.2.2) where this particular Scrivener project will open with nothing showing in the Binder even though there are documents open. I don’t know how this occurs but when it does, it’s on the first opening of the project.
The only way to remedy this is to close the project, then quit Scrivener application, then re-open the project. And sometimes I have to do this multiple times.
I’ve attached a screenshot of when the binder looks empty.
