Companion no funciona

Hello, I am a new user of android builder, very good and promising, the project looks but I have tried to create an app when viewing with the companion, it never opens, I tried to uninstall and install without success, it still does not work, apart from when I edit the visual part it does not work it shows everything and I can’t continue editing because it won’t let me introduce more materials to the visual part
