Modpack Version

1.83

Describe your issue.

It loads, says building terrain, then shutting down internal server and crashes after around 10 seconds.
I have tried restarting my computer and downgrading to forge 1.12.2.14.23.5.2768, but that didnt work.

Have you modified the modpack?

Yes

User Modifications

I have disabled foamfix and re enabled it but that did not work.

Did the issue happen in singleplayer or on a server?

Singleplayer

No, I do not.

Try downgrading java to version 311 or 312 :D
321 is known to have a lot of problems with minecraft.

Does not work
Crash Report

Well crashlog reports that you are still using 321.
Java Version: 1.8.0_321, Oracle Corporation

Make sure you delete java 321
Control panel-->Programs-->Uninstall programs-->Search for java, right click, then uninstall

Crashed again
Crash report

Thankfully, it's not a java crash anymore

Thanks for the report.
Quick question - You have a Minecraft account right? :)

Then I recommend you get one. That should fix your problem too.

I do not have the money for that, I would if i could.
Also, i forgot to mention: The mod pack used to work 2 days ago but yesterday it stopped working

That's too bad, unfortunately we do not offer support for cracked clients.
If you still have a problem after acquring a legitimate account at some point, you can of course ask again.

Just wanted to report that this crash happened with me, even tho i have a mc account. It only happened once and it still didn't happen to me again.
