Summary of the problem World Crashes Upon Entering

Is it repeatable? Yes, anytime I enter it doesn't work. This glitch is also found in multiple other mod packs, and the only one that there is no glitch is Agrarian Skies 2.

Known Fix None.

If you have a dedicated GPU make sure Java is set to use that, otherwise update the integrated GPU drivers.

I updated my drivers and made sure Java is on my GPU, but it still doesn't work.

I tweaked around a little bit and might have potentially made some progress, but I can't read code at all. Is this a step in the right direction?
