Back Camera 1 lense / and flashlight suddenly stopped working on iPhone 13 pro

Is this covered under warranty? I have lense protection and an otter box no damage phone is still new battery life is at 100% capacity and out of the blue yesterday it stopped working, will I have to pay for something I didn’t do or is this under warranty? I have an appt t Best Buy but don’t want to waste time if they wanna charge me.
