With the awesome update made to 1.18.x is such a shame I can't make it work. The game just crashes throws this log:

The game crashed whilst initializing game
Error: java.lang.RuntimeException: Mixin transformation of net.minecraft.class_329 failed
Código de error: -1

Minecraft version: 1.18
Fabric version: 0.12.12

Latest Iris + Sodium are installed

I will look into this,

I cant seem to reproduce your issue. Can you provide a full mod list along with your .minecraft\config\sodium-options.json and .minecraft\config\iris.properties files?

Sodium

This is a direct conflict with Flour's Various Tweaks (fvt-fabric-1.8.0-mc1.18.jar), it adds a feature that is not compatible with this mod.

Perfect, thanks!
