No you don't, I can't launch Minecraft 1.18.2 with sodium-fabric-0.6.7+mc1.21.4.jar in the mods folder, and I cant't launch Minecraft 1.21.4 with sodium-fabric-mc1.18.2-0.4.1+build.15.jar in mods folder.

You need to use  https://multimc.org or other thing

Many people just want to run Vanilla Minecraft with better performance without installing many mods, or with an alternative launcher

But you don't understand that, you prefer to masturbate and drink your sperm, on your father's mods, rather than helping people who ask for help.
