So, I don't know when it happened, but it looks like the editor crashed. There aren't any sprites, and I can't place any blocks. However, if I go to the Costumes tab, the costumes are still there, and the same goes for the Sounds tab. The Backdrops tab also works, but the Code tab doesn't. When I press the green flag, I can hear the project running, but I can't see anything. Does this happen to you too?
