Right click CSING Issue # GAMEPLAY], [CLIENT], [CRASH],

So Idk if this is my problem or just the league problem. Whenever I play like 3 or 4 games. Then in the middle of the game, my right click is not attacking to any objective accept champion. What it mean is Whenever people move their mouse to any objective( Minions, turret, and jungle monster) that the mouse will become like a red sword. Means if you right click on it will attack but it official does show up to me. Everything change when I am in middle of the game. Can't CS right, Can't attack right. I try to go on my setting which is making my setting more mess up. So I hope riot can fix it.
