[MC-44462] Can't play on servers or any single player worlds

I expected to just log in and play my survival world and my server!

But when I load any world my Minecraft client just crashes

1. Open Minecraft
2. Load a world or log in to a server (Survival and creative)
3. CRASH

I fixed it! Had to re install Minecraft, restart computer and then restart again.
