Game crashes upon joining world/server

Minecraft Version 1.11:

Game crashes as soon as I load a world, I get " Game ended in bad state (exit code 255)".

And when I try to join a server, I get the message:

1. A fatal error has been detected by the Java Runtime Environment:
   #
2. EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x000000001acac933, pid=6336, tid=3260
