The CreateFanMixin file is this:
 

package com.guniks.reimagined.mixins;

import com.simibubi.create.content.kinetics.fan.processing.AllFanProcessingTypes;
import net.minecraft.world.item.ItemStack;
import net.minecraft.world.level.Level;
import org.spongepowered.asm.mixin.Mixin;
import org.spongepowered.asm.mixin.injection.At;
import org.spongepowered.asm.mixin.injection.Inject;
import org.spongepowered.asm.mixin.injection.callback.CallbackInfoReturnable;

import java.util.Collections;
import java.util.List;

@Mixin(AllFanProcessingTypes.BlastingType.class)
public abstract class CreateFanMixin {
	
	@Inject(at = @At("HEAD"), method = "canProcess", cancellable = true)
    public boolean canProcessDisable(ItemStack stack, Level level, CallbackInfoReturnable<List<Boolean>> cir) {
        cir.setReturnValue(false);
    }
	
}

Can anyone help please?
