Sorry to hear it. I'm afraid you'll need to do a factory reset on the console to fix this issue. There's an option to keep installed games and apps and your saves will be safe on the Cloud. You can read how to do a reset via this link https://support.xbox.com/en-US/xbox-one/console/reset-console-to-factory-defaults
