Number 3 doesn’t work.

I can’t type out the number ‘3’ on my keyboard using the top row of keys, only the numpad, so I bought a new keyboard.

The thing is, it didn’t solve the problem. New keyboard ‘3’ doesn’t work either, but numpad does. Any ideas what I could do to troubleshoot this?

I’m using Windows 10.

EDIT: It works if I start in safe mode.
