Client Crash [GAMEPLAY] [CLIENT] [CRASH]

At first I thought it was my laptop in need of a update until today. Everything works fine until I accept a match. the loading screen never shows up for either SR or TFT. the champions are usually displayed with the loading bar at the bottom but all I get is a complete black screen. I even heard the match start and my friends fighting. I was sitting there for about about 7min after it started not including the 2-3min used for loading. I couldn't even exit the game to restart it. I had to completely shut down my Laptop. I believe a crash report has been sent but really not sure if it worked. I will try un- and reinstalling the app to see if that works.
