Screen play stopped working

hello, i used to download only games from steam but a friend of mine showed me screenplay and i downloaded it, it did work at the beggining but after sometime it stopped i start the screenplay and after that window on steaming that says starting it never opens just close and i don’t know what to do

Hi, can you check your Windows tray icon if Screenplay is listed there?

Captura de Ecrã (52)
no it isn’t but how can i list it

It might be that steam icon?

i tried the steam icon

but once i click on screenplay it trys to open it with no sucess
