Keyboard randomly quits working

So randomly the game will just decide it doesn’t want to read my key inputs. This will happen seemingly erratically and after loading into the game, no key shortcuts work. I can buy items and everything but to use any abilities, actives, etc., I would have to click the icons then click to aim them making the game incredibly difficult to play. It used to go away after a dc and rc or alt+tab out and in but now I have to restart client entirely. This seems to have also happened to people here

I have tried the solution but it only worked temporarily.
