Cant acess the project anymore

My chat window I was working on and iterating went completly black and wont open anymore. I paid a sub for this exact project, and now all the work is gone

Someone mentioned to try to fork the project, but I cant even open the project to get to the top bar to see the forking options.

After clicking on the project, the app is not changing at all, if I get to the project with a link, the screen is completly black.
