whenever i try to launch fabric 1.18.2, this happens

Uncaught exception in thread "main"
java.lang.LinkageError: loader constraint violation: when resolving method 'org.slf4j.Logger com.mojang.logging.LogUtils.getLogger()' the class loader net.fabricmc.loader.impl.launch.knot.KnotClassLoader @604c5de8 of the current class, net/minecraft/client/main/Main, and the class loader 'app' for the method's defining class, com/mojang/logging/LogUtils, have different Class objects for the type org/slf4j/Logger used in the signature (net.minecraft.client.main.Main is in unnamed module of loader net.fabricmc.loader.impl.launch.knot.KnotClassLoader @604c5de8, parent loader net.fabricmc.loader.impl.launch.knot.KnotClassLoader$DynamicURLClassLoader @5fe1ce85; com.mojang.logging.LogUtils is in unnamed module of loader 'app')

does this only occur with fabric loader13.3, fabric api 0.47.10+1.18.2 , and no other mods?

If its not iris, it will be some other mod bundling sfl4j which is now "included" by minecraft itself as 1.18.2.

This is not a fabric api issue. If it were a fabric issue at all it belongs in the fabric-loader issues.
e.g. the fabric-loader could in principle exclude any slf4j classes from mod jars to avoid this problem
