404 Settings not found

I’m trying to open my project:
PlayCanvas | HTML5 Game Engine,
PlayCanvas | HTML5 Game Engine,
but it shows a 404 error “Settings not found”. Why is it happening?
404

Did you delete the project? is it not your own?

In addition to the above, the scene could be deleted, the project is now private (assuming you are not the owner).

Are you opening your projects from the dashboard?
