I launch Minecraft (No Mods) and play single player. When I join my world, it loads up and I can play just fine until after about 15 seconds the screen freezes and the music keeps going. I close the tab and the launcher tells me that the game has crashed. I have tried running MC as administrator and it still has not worked as well was uninstalled and re-installed but the problem still occurs. The last time I can remember successfully running MC I was on a plane coming from China to Canada (I'm not sure if this is relevant). I recorded the Debugger twice and this is what is gave me:
