Assignment project not loading - relaunch already tried.

Hi. I have a student who was nearly done with their assignment when the rstudio.cloud page refreshed. Since then no one (neither the student nor the two instructors who have access) has been able to open the project. All three of us have tried opening the project and tried relaunching the project to no avail. Suggestions?

The project is https://rstudio.cloud/spaces/24707/project/480510.
