I've had a modpack for about 6 months now and everything was working out fine but recently i tried updating the modpack so i went through the process of taking out mods that were negative and added a few that seemed beneficial for gameplay but when i tested the modpack out on minecraft the game would load fine but whenever i tried to load or create a world the game would take a minute and then say "shutting down internal server" so I kept taking out mods i added and replacing mods i took out until i completely reverted the modpack to the way it was before i updated it and the problem continues. I'll post images of the old modpack update, the new modpack update, and the crash report I get every time this happens. The crash report said to try removing ender IO so i did and nothing changed.
