game seems to crash randomly

either before a game starts it crashes before the loading screen or during a game it crashes randomly first it appears i disconnect then i exit the game and it says it crashed I try to reconnect and it just keep crashing and after many attempts im able to rejoin the game and it can crash again later during the same game. I don't have lolreplay installed and its only happened since this patch im repairing my game and hoping it fixes it not sure what the problem is anyone having the same issue as ive seen people in games just disconnect and then not re-join probably due to not being able to reconnect
