[GAMEPLAY] Random Freezes Late Game.

Basically my client randomly freezes up even though it has never done this before 4.20 and I get 60 fps. It will completely freeze and If I alt tab it shows a black screen. I basically just have to wait it out whenever it freezes because I cannot close the client either with anything even if I use task manager to try and close it. It usually lasts 2-10 seconds longest around 30 PLEASE FIX :)
