[Client] Launcher Freezes PC
Since the last major patch (so for roughly a week or so), whenever I launch LoL the first time, it instantly locks up my PC for anything from 30 - 60 seconds. During this time background activities continue to happen (music continues to play, etc.) but I have no control at all over my PC and the mouse cursor will not move. After 30 seconds or so I get control back, but LoL will not launch and I always have to manually kill it, despite it showing up in Task Manager.
The second or any subsequent launch, the game works fine and there is no issue. Once I reboot, same issue, and the first time locks up my PC again, and so on and so forth.
I tried a repair yesterday hoping that would fix it, but the same thing happened when I launched just. LoL is the only game this happens with, and as I said, only since the last patch a week or so ago.
