Okay, this is going to sound crazy but here goes. I have had this issue for months. It didn't appear after any specific updates, I don't have any chrome extensions (the most common explanation), and I have been unable to fix the issue after numerous restarts, resets, re installs etc etc etc. I just gave up and said to myself, hmm. I wonder if there is a way to check whether this very specific set of keys somehow broke all at the same time. I googled "keyboard key tester" and clicked the first link. My skip and pause keys IMMEDIATELY came back online. I can't believe it. After so so much playing around, this fixed it. I'm posting this here to hopefully help someone, and would also be incredibly curious if it works for anyone else. This is the link I used: https://en.key-test.ru
