MacBook Air M1 keys from 1 to 9 not working on the keyboard

Dear Apple Support Community,

I have just gotten the MacBook today, it is brand new (if that means anything) and I am having issues with my built-in keyboard. When I press on any of the numerical keys, the MacBook is unresponsive meaning that the character is not typed on the screen. The numbers do occasionally work for a couple of minutes and then it is the same issue again. The mouse keys and the slow keys are not turned on, I have already googled the issue and none of the solutions that were provided to me work. I am currently using the on-screen keyboard to type the characters but I find it to be very inconvenient. Could this be a faulty hardware issue and is my MacBook eligible for a free replacement under the warranty if that is the case?

Thank you,
