I just started on trying to teach myself how to download/install mods and such for Minecraft, and I'm already failing miserably. Upon trying to open Minecraft Forge in Minecraft vJava, it will load most of the way until it gets stuck on Atlas stitching for shulker boxes, and it will loop the percentage/amount of data downloaded. The only mod I have downloaded is BSL shaders (downloaded from https://www.curseforge.com/minecraft/customization/bsl-shaders/download), but this problem was happening before I had the mod.
These three lines stick out to me as incorrect, but I either don't know what they mean or don't know how to fix them.

And this is the entire debug log.
