Queze ~ Thanks for the feedback. Please indicate what happens when you tap on an app icon to open it. ...Do you get an error message or nothing happens?

Are you able to interact with the screen in other ways – such as opening Control Center by swiping down?

Did you restart your device as the Support Article suggested?

...The more details you can supply, the better help you'll get here – thanks.
