Minecraft will not create a new world.

I've recently have been in the mood to play minecraft which has worked perfectly in the past, but every time i try to create a new world on single player it loads for a few seconds and then crashes. I have uninstalled minecraft plenty of times I have even tried the older launcher to see if that was the case. I have also completely removed java and re installed it (current version Jre1.8.0-141) and i have also completely updated my graphic cards, turned off my firewall,and disabled and lan creators (hamchie,evolve ect.). But i still get crashes. can anyone help... here is my crash report.
