A critical error has occured..

Hello. For the third time in a ranked game, the game freezes and i get this message which gives me no choice but to manually reboot the pc. I know this is a problem from the game and not my pc, because it only happens in lol, and i have seen many others with the same problem. Could riot fix their game instead of making one useless skin after the other. Thanks!
