Aurora R16, keyboard woes

I just bought a new computer; an Alienware Aurora R16, and I was setting it up, and everything was fine. I went through the whole win11 setup process - named the computer, set up a PIN, etc, no issues, but then, Windows started, and now it won't take input from my keyboard. I ran winupdate, I uninstalled and reinstalled the keyboard driver, I tried "sfc /scan now" but nothing seems to work. I've plugged in multiple keyboards, but none of them will create any input after the Windows login screen. Am I going crazy?
