Game crash (riot , answer to mypost and explain what is going on because i'm sure it's not my fault)

Please riot, fix your goddamn game!!!!!!!!!!!!!!!! Every week my game crash multiple times, and the only one solution is a pc restart which takes time and causes me to wait 20 min per game. I have seen people talking about this problem in a month ago, so its not my fault. My specs are enough good for the game. Processor Intel(R) Core(TM) i3-6006U CPU @ 2.00GHz Video Card NVIDIA GeForce 920MX Video Card #2 Intel(R) HD Graphics 520 RAM 6.0 GB Operating System Microsoft Windows 10 (build 17134), 64-bit

Sorry if my London sucks lul
