Recovering past version of a project

I'm teaching a course using RStudio Cloud, and one of my students reported that upon opening one of her projects, the files were still listed under the "Files" tab, but when she opened them, all of the text was gone. Is there a way to recover an earlier version of her project before this happened?

Unfortunately, no, we do not keep a history of the files in the project. RStudio Cloud does not auto save, so it is possible the work wasn't explicitly saved prior to closing the project.

thanks
