Game crashing when joining world with Iris installed.

[inkobee]

When I run the latest stable release of LiquidBounce NextGen, everything works fine, but I can't join a world, or the game will crash. I noticed this happened after installing Iris.
Does anyone know what happened? I know for sure that Iris is causing it. I double-checked that all mods where for the 1.21.1 version, and I tried disabling some. Here are the mods I am using:

Built-in:

• NoChatReports
• Reese's Sodium Options
• Sodium Extra
• Sodium
• ViaFabricPlus

Separate:

• Cloth Config
• Collective
• Continuity
• Entity Model Features
• Entity Texture Features
• Fabric API
• Fabric Kotlin
• Hide Hands
• Indium
• Iris
• Mod Menu
• Noisium
• Skin Shuffle
• Subtle Effects
• Text Formatting Everwhere

I don't know how to fix this, but I really want to use shaders. If I could get any help, it would be greatly appreciated. Thanks!
