Client crashing when queue pops

Since 7.11, about 50% of the time when my queue pops the client bugsplats and I have to relog and re-queue all over again. Counting 7+ minute queue times and dodges, I'm often waiting 30+ minutes between games. This issue also happens occasionally during champ select and has happened several times as the game is about to start (after timer hits 0). Note that I do not get queue dodge penalties when this happens (I can immediately re-queue upon relog). Has only been happening since last patch.
