After starting the game the output log viewer stays open for a short while in the main menu and then crashes with a Windows error. Upon clicking on debug it says that "An unhandled win32 exception occured in MinecraftLauncher.exe [3744]." The process seems to also be the same as the one that uses a lot of cpu performance before the crash occurs. After the crash the output log viewer window stays open but doesn't respond anymore.

The nativelog doesn't seem to contain any errors but I'll add it anyways.
