The game app is loaded on your phone, but have not been able to open the game for 1 year? Have you tried doing a soft reset. Sign out of your game, turn your phone off and let it set a few seconds, the log back into your game with your email and password. See if then you can open the game.
The only other thing you can do is delete your app, then reinstall the app. Just a heads up, when you uninstall the app you will loose all of your boosters. But that is the only option you have. Again, please check to see if you have enough GB's to run the game app. 🤗
