Project won't open - stuck on 'opening portal'

I have a class that use gdevelop as part of their project for creative media. One of the students has logged into their account this week and been unable to open their project. It consistently gets stuck on the ‘opening portal’ part of loading. We’ve tried multiple pc’s, some with different specs and the browser version and the problem occurs everytime. The file is saved on the cloud. Does anyone have anyway we can recover this file?

Thanks
