LoL crashing again and again in loading screen

Hello,

This is the first time has ever happend to me. I was in champion select as usual and the game started. I went to loading screen and the game crashed. I thought "nothing unusual, this happens", so I clicked on the Recconect button. 2 seconds after clicking it, I got kicked out of the loading screen again, seemingly without any reason. I closed the game from Task manager and tried again, same result. I restarted my laptop, same result. My teammates remade the game obviously and I got deducted points for something I could not control in any way. Has this ever happend to anybody else? If yes, how did you manage to fix it?
