[Client] [Gameplay] Borderless window mode = can't play anymore.

Hey, for the past few weeks I've been having problems. I can't change my settings back....because the game crashes every time I try to load into the game....then no matter how much times I reconnect or anything...it crashes. Then I can't do anything except wait in a ranked game...AFK..BECAUSE I CAN'T PLAY. When I try to end it, it takes about 3 mins to respond and close the exe...then it says sending errors. then I can't play...It's really annoying. I rejoin all i get is a hourglass hand for loading, then about 100% later...it goes black and then crashes. it wont even load into the game... well there goes my low priority cue and a lot more because of this "Borderless windowed mode" not even working just crashing.

UPDATE! Then it gets to 100% and can't connect to the internet...when I'm on it...can play any game online...even since I have everything though my fire wall and everything... it says "You have been disconnected. Please check your internet." every time and I can't play anymore YAY!

UPDATE+! It says "Game is still going" for about 5 mins before it comes up with a message saying "Your game has crashed. please try to reconnect." and it repeats.

Final update..I hope

every 10% loading the screen flashes black then goes back to the game then loads then flashes. just the game though not windows or any other game.
