League crashing to dekktop at end of game/post game.

My League client keeps crashing every so often after the game ends and you get a victory notice or once it goes to post game. There's no bugsplat warnings either whereas before it was doing it during and after games pretty much regularly. I've fixed the in game crash by rolling back the Windows insiders preview to prior release which several people confirmed was an issue as well. My video drivers just got updated so I'm going to try and roll those back and see what happens.

This really sucks for SR because you can't see how good you or your teammate(s) did especially when you win. You also seem to lose any chance at keys/fragments etc and I'm unsure if those count towards afking since they happen so close to the end of game.
