Unable to click in game

Ok so when I got in game I was unable to click or rclick anything. I tried reloading the game then reloading the whole application but that didn't work. I saw a forum post where they had the same problem and their solution was to toggle off the discord overlay. I did this and nothing happened. I'm playing on PBE so I don't know if this is a different bug or what, but nothing I've been trying has worked at all. Does anyone have a different solution?
