In Game Freezing [Crash]

I am playing on a Windows 10. Occasionally, the game freezes in the middle of the match. I forcibly close the client and the gameplay window with task manager and try to relaunch the client. However, the client does not launch. I have tried repairing the client already, but this still happens to me, which is frustrating because it has cost of a couple of games already. This has only started happening to me ever since patch 7.9 was released. The only solution I have to this is to forcibly shut down my laptop, turn it back on, and reboot League of Legends. If there is anyone who has this problem as well, I would gladly welcome any help.
