Some players are running into an issue where their Xbox One controller becomes unresponsive. This can occur for the first time at the Title Menu or in a game when opening inventory or menus.

Xbox One

Title Menu: Restart Grounded or plug in a keyboard to get past the welcome message.

In-game: Restart Grounded.

Some players have also mentioned that if a second controller is connected, it may need to be turned off as it can take over some controls.
