Minecraft with forge crashes when loading up a world and going into Multiplayer

[Czibi]

I have tried installing with the installer and without, and yes, I have tried backing up and deleting my .minecraft, but this error still happens. I am using the latest build of forge. Apologies if this has been posted before, I have looked through but the only posts I've found are from older versions. Feel free to remove it if it has already been answered.

Random guess, you're using avast anti-virus? Try disabeling your firewall.

{Even if not using avast try it} Thats what usually causes this error.

I'm not using avast and i disabled my firewall. Same thing.

Interesting, this StackOverflow might be relevant. Try adding -Djava.net.preferIPv4Stack=true tot he vm arguments in the profile config.
