Project opens in RStudio Cloud, but freezes


I am having trouble in accessing a project for a while in RStudio Cloud. I can open the project, but nothing else. I cannot either relaunch the project. It is all frozen. Yesterday I have some trouble with, it threw "no such directory" sometimes, but I could relaunch. Now, I can do nothing, even relaunch the project... I already tried to clean the navigator's cache...

Thanks for any help!
