Not able to use League Game window

So I was starting up another game for League Ranked after coming back from my last one, just sitting there waiting to get in, and as soon as it comes up, I'm already trying to get started and get moving, but I can't move or press anything at at all in the game. Its stuck with my default desktop mouse cursor on the screen and the League one will not come up, and I cant even press the GUI buttons in the game, I tried leaving and coming back by using End Task on the Task Manager, but when I come back its still doing it, I tried coming back three times but its not working. I'm posting literally after doing it right now, checking for any solutions or if anyone else is having this problem because I'm most likely going to get punished from the game saying I left and quit the game...any help or info is appreciated. {{sticker:sg-soraka}}
