This is a good option to try if the console freezes, or won't respond:
- Remove the console from the dock and attach the Joy-Con controllers.
- Hold down the Power Button for at least 12 seconds to force the console to power off.
- While the console is powered off, remove any game cards or microSD cards.
- Power on the console and perform a system update.
- Attempt to navigate the menus and start Rocket League.
