Some keys are not working on my Macbook Air M3

Hi, recently some of my keys not working (enter, right command, right and left arrow, etc) on the right side of my mac. Yesterday all of those keys working perfectly fine, and suddenly it stopped working. I don't know what to do since this mac is my first mac and it seems i used it perfectly safe (never spilled anything or drop my mac). I haven't been able to find what might be causing this problem. Do you have an idea of what it is and how to fix it? Thank you!
