Trackpad and Keyboard not working after three months of usage

Hello, just this month, after online class, my macbook Air M1 keyboard and trackpad are not working. I locked the screen after class for about 30 minutes, and when I turned it on, I found out that only the touch ID button is working. The 'buzzing' feedback of the trackpad is gone. I don't know what happened to it, I never have let it get wet nor did I ever let it fell. It stays in a nice and cool room to avoid overheating. I tried all possible things to make it work but unfortunately none of it work. Can someone help me fix this problem pls. Thank you.a
