I've recently installed the latest version of aether 2 along with the Orbis API but can't play it since it keeps crashing once I make a new world, any advice? Here the crash report

You are on the wrong forum. The problem is caused by the mod itself, not by Forge. But of course, I can give you some tips.

1. Report the issue to the mod author, what was already done a week ago here. You can help the mod author by providing your logs, so he can fix the bug in a newer version

2. Use an older version of the mod where it may works.

3. Delete the mod and use one that provides similar features (For example Aether legacy)
