Why is my galaxy note 9 restarting and locking up

[Android Central Question]

My note 9 keeps restarting after a about 9pm randomly it shows that pad lock with a circle going around it for about a hour then turns back on any idea of what's caused this

Check in device care if you have it scheduled to restart at certain time.
