Game crashes when I load a shaders pack for 1.20.1 version of Minecraft

Hi! So uh, I'm having issues with Iris for Minecraft 1.20.1

I can use the mod just fine and it doesn't crash my game until I click on one of the Shaders I have installed. For some friends the shaders work just fine, no crashing, no problems. Iris and shaders works completely fine for me when I use Iris for 1.19.4 or below with any shaders pack. I use the ATLauncher modpack launcher to play Minecraft, and of course again, Iris works perfectly fine, shaders works perfectly fine but only 1.19.4 or below.

I've made a new instance with no mods, no texture packs, nothing besides just Iris, Sodium, and shaders packs to test if it's a mod I use that's causing the crash. It's not. If I click on a shaders pack to use it, my game crashes instantly.

I'm going to attach both the stuff shown up on the ATLauncher Console and the actual game crash file. Once again, I've asked friends who use shaders if they have the same issue and they don't. I literally have no idea why it's crashing.
