The game crashed whilst there was a severe problem during mod loading that has caused the game to fail
Error: net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from Loot Bags (lootbags)

Modern Skyblock 2 is a 1.11.2 pack, so you need to use the 1.11.2 version of Lootbags, not the 1.12.2 version.
If you mean Modern Skyblock 3, it already has Lootbags in it.

Also, post the entire crash log, not just the first couple of lines, otherwise I can't help with it.
