Hi there!
So i am currently experiencing problem where i am trying to start Modded Minecraft 1.7.10 ( Agrarian Skies 2). The Problem is that it crashes and i don`t know how to fix it.
Note that i added 4 mods. But these have to be in this pack because otherwisemy Game spits graphical errors like hell (like The Screen beeing a solid color, textures not loading properly etc.)
These 3 Mods are:
lwjgl3ify
Hodgepodge
GTNH Mixins
GTNHLib
The Modpack on itself https://www.curseforge.com/minecraft/modpacks/agrarian-skies-2
Here is the crash report:

Hmm, it seems like there's a conflict or issue with the mods you've added, particularly related to how the game loads and processes the code (classes) provided by mods when it starts up. looks like the error message indicates that Minecraft is failing to find a class
(cpw/mods/fml/common/event/FMLConstructionEvent)which basically means that there might be a compatibility issue with one of the mods you've added, maybe change the mod load order? or try removing one of the mods and see if that fixes your issue.1
Hey, so when i remove the mods, then minecraft loads up, but then i have graphical errors as previosly stated. It has sth do with my Computer and the Intel Iris Xe Graphics (iGPU).
But what do you mean by changing the modloader, like another version of Forge? Or sth like Fabric?
Also thank you for taking you time and try to help me out, i appreciate that very much! (*^_^*)
