I can't seem to find the problem here...

Hello all, once again I need some help.
For my plugin: Backpacks++ I have a listener that check for backpacks and stuff and there is a recipemanager that enables backpack recipes, adds the name to a hashmap but there is a weird "bug", you can't open backpacks, you can only register new ones...And the player gets this message:This <type> is not loaded because it was not defined properly. ......Here is the code, if someone sees the problem, (really I can't find it)

Code:

package me.captainbern.backpack.listeners;
 
import java.util.HashMap;
 
import me.captainbern.backpack.Main;
import me.captainbern.backpack.command.commands.SeeCommand;
import me.captainbern.backpack.pluginutils.BPEnchantment;
import me.captainbern.backpack.pluginutils.exceptions.Logger;
import me.captainbern.backpack.utils.BackPackUtils;
import me.captainbern.backpack.utils.WorldUtils;
import me.captainbern.backpack.utils.recipeutils.RecipeManager;
