Linkage Error

Ever since I updated Quilt, Minecraft, and my mods to 1.19.2, whenever I load Minecraft using Quilt, I get this message:

LinkageError: loader constraint violation: when resolving method<br>'org.slf4j.Logger com.mojang.logging.LogUtils.getLogger()' the class loader<br>org.quiltmc.loader.impl.launch.knot.KnotClassLoader @5aac4250 of the current class, net/minecraft/client/main/Main, and<br>the class loader 'app' for the<br>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 org.quiltmc.loader.impl.launch.knot.KnotClassLoader @5aac4250, parent loader org.quiltmc.loader.impl.launch.knot.KnotClassLoader$DynamicURLClassLoader @6b3e12b5; com.mojang.logging.LogUtils is in unnamed module of loader 'app')

I originally thought it was Architectury, since removing the mod brought me to a white screen instead of just crashing. However, now that I’ve updated to the latest version of Quilt, I get the same message even without Architectury, leading me to believe that’s not the real issue.

Here’s the log:

It might be worth updating Loader to be safe, generally issues like this are loader-related, and I think we’re at .6 now

Still getting the same issue:

I’ve been trying to figure this out but no luck so far - I’ll try to light a fire under someone with more knowledge than myself.

This is an… Interesting error. I would blame loader for this, but it could also be a very invasive mod.
If you could test some stuff that would be great! If you can try to remove as many mods as possible while still producing the same error, that would be very helpful.

I would start by removing all mods, as a sanity check. After that, try removing half the mods, check of it still crashes and then repeat with the set of mods that cause the same crash.

Sorry that I don’t have a direct solution here. We somehow end up with multiple loggers, I don’t really know how that would happen unless a mod touches Mojang logging very early.

If this isn’t a mod issue, I’ll forward this to our loader team.

Heya @equarius! This may not be the issues, but from my experience baritone doesn’t work on quilt. Try removing that

Having chatted a bit on Discord, someone pointed out that you’re using Meteor client. Aside from being unable to support clients like Meteor, it’s worth pointing out that many clients like that break all kinds of things.

I’ll close this topic now, since you’re using software we can’t help you with.
