Question about Apple's limited 1-year warranty--webcam randomly stopped working.

Hello.

Have an M1 Macbook air that is still covered under the limited warranty until that comes with the computer, not referring to Apple-Care. But one day I went to use FaceTime, and now it says every time: No Camera Available. To use FaceTime Camera, connect a camera.

Anything anyone can tell me about whether or not this is covered?

Thank you,

John
