Up and Down Arrow Keys Not Working on MacBook Pro M1 Max

I got a new MacBook Pro M1 Max a few days ago. I just noticed that my up and down arrow keys are note working. It’s running macOS Monterey 12.0.1. This is happening in all applications. I have tried disconnecting all accessories and other devices and rebooting. That has not fixed it.


Typically, I would reset the SMC, but apparently this doesn’t exist on the M1 chips. I'd be grateful for any help.

MacBook Pro (2020 and later)

Open keyboard viewer (Open System Preferences>Keyboard>Input sources and click on show input in menu bar, then click on the keyboard icon in menu bar and select show keyboard viewer. )

Press on the arrow keys and side if the virtual keyboard shows those keys being depressed.
