Hi @Grock71,
Welcome to the Roku Community.
It's unfortunate to hear about the issue you are experiencing. We'd like to know more about how we can help. Have you tried to restart the device from the Settings menu by navigating to Settings > System > Power (If you do not see a Power submenu, skip to the next step.) > System restart?
Keep us posted on how it goes.
Regards,
Nimfa
