When using Paladin's Furniture (v1.1.4) and Patchouli (v79) the game crashes and I get the following error

java.lang.AbstractMethodError: Receiver class com.unlikepaladin.pfm.compat.forge.patchouli.FurnitureRecipeProcessor does not define or inherit an implementation of the resolved method 'abstract void setup(net.minecraft.world.level.Level, vazkii.patchouli.api.IVariableProvider)' of interface vazkii.patchouli.api.IComponentProcessor

The same thing happens to me

Same to me.
This is the log:

The game crashed whilst unexpected error
Error: java.lang.AbstractMethodError: Receiver class com.unlikepaladin.pfm.compat.forge.patchouli.FurnitureRecipeProcessor does not define or inherit an implementation of the resolved method 'abstract void setup(net.minecraft.world.level.Level, vazkii.patchouli.api.IVariableProvider)' of interface vazkii.patchouli.api.IComponentProcessor.

The same thing happened to me. The crash is on the client side.

You'll have to remove Patchouli until I fix this, because I updated long before them to 1.19.4, they made changes to their API that I couldn't account for so it's incompatible with it for the moment. Quite ironic.
