1.16.5 Why can't my enchantment register?

So I'm working on a enchantment called smelting, and i cant register the enchantment. here's my code: (i've tried to directly call registerEnchantment(), but doesn't work either) my other enchant, telepathy, works fine. It turns out there was some exception
CustomEnchants.java

Code (Java):

package net.wardensmp.plugins.enchantments;

import org.bukkit.enchantments.Enchantment;

import java.lang.reflect.Field;
import java.util.Arrays;
import java.util.stream.Collectors;

public class CustomEnchants {

    public static final Enchantment TELEPATHY = new EnchantmentWrapper("telepathy", "Telepathy", 1);
    public static final Enchantment SMELTING = new EnchantmentWrapper("smelting", "Smelting", 1);

    public static void register() {
        boolean registered =
                Arrays.stream(Enchantment.values()).collect(Collectors.toList()).contains(CustomEnchants.TELEPATHY);
        boolean registered1 =
                Arrays.stream(Enchantment.values()).collect(Collectors.toList()).contains(CustomEnchants.SMELTING);
        if (!registered) {
            registerEnchantment(TELEPATHY);
        }
        if (!registered1) {
            registerEnchantment(SMELTING);
        }
    }

    public static void registerEnchantment(Enchantment enchantment) {
        boolean registered = true;
        try {
            Field f = Enchantment.class.getDeclaredField("acceptingNew");
            f.setAccessible(true);
            f.set(null, true);
            Enchantment.registerEnchantment(enchantment);
        } catch (Exception e) {
            registered = false;
            System.out.println("?");
        }
        if (registered) {
            System.out.println("Registered enchantment" + enchantment.getName());
        }
    }
}

return plugin;

my event that detects the smelting thing, if you need it:

                        } else {

                                || result.getType() == Material.EMERALD) {
                            return;
                        }
                    }
                }
            }
        }
    }
}
