League bug with discord app [game play] [client]

I was loading into the match and decided to alt tab to watch a video while I waited ( I use full screen) and when i tabbed back in we loaded into the game but I noticed that I was unable to move or type in game, I disconnected my keyboard and mouse and reconnected them but it didn't fix so i decided to close the client and restart I did this about 3 times and it didn't fix so I decided to close discord and then restart the client and when I did that I was able to move and type to my team. Pretty scary bug since I loaded into a ranked game and couldn't play for like 6 min would advise looking into this bug might be a prob with the discord app overlay when loading in and alt tabbing in full screen ( not sure if this happens on the other screen sizes). Hope this helps fix an unknown bug.
