after i play the game for a little while the game get stuck on the "k" key. I dont know what is causing it, but i know it's not my keyboard because i replaced it. Can someone please help?

How hard do you push down on the key, if you press hard you might jam it.

This used to happen to me with the h key at the beginning of a round. When all the files were loading in-game, I held down the effected key, and it stopped.
