1.20.1 Help. My config file is broken.

[the_BigGinge_nafe_innit12]

I was adding a new block, i finished it and then out of the blue my game won't load and my config file is broken. It tells me that it can't convert a string into List<string>.

Here's the config file.

import net.minecraft.resources.ResourceLocation;
import net.minecraft.world.item.Item;
import net.minecraftforge.common.ForgeConfigSpec;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.event.config.ModConfigEvent;
import net.minecraftforge.registries.ForgeRegistries;

import java.util.Collections;
import java.util.List;
import java.util.Set;
import java.util.stream.Collectors;

// An example config class. This is not required, but it's a good idea to have one to keep your config organized.
// Demonstrates how to use Forge's config APIs
@Mod.EventBusSubscriber(modid = ChippyMod.MOD_ID, bus = Mod.EventBusSubscriber.Bus.MOD)
public class Config
{
    private static final ForgeConfigSpec.Builder BUILDER = new ForgeConfigSpec.Builder();

    private static final ForgeConfigSpec.BooleanValue LOG_DIRT_BLOCK = BUILDER
            .comment("Whether to log the dirt block on common setup")
            .define("logDirtBlock", true);

    private static final ForgeConfigSpec.IntValue MAGIC_NUMBER = BUILDER
            .comment("A magic number")
            .defineInRange("magicNumber", 42, 0, Integer.MAX_VALUE);

    public static final ForgeConfigSpec.ConfigValue<String> MAGIC_NUMBER_INTRODUCTION = BUILDER
            .comment("What you want the introduction message to be for the magic number")
            .define("magicNumberIntroduction", "The magic number is... ");

    // a list of strings that are treated as resource locations for items
    private static final ForgeConfigSpec.ConfigValue<List<? extends String>> ITEM_STRINGS = BUILDER
            .comment("A list of items to log on common setup.")
            .defineListAllowEmpty("items", List.of("minecraft:iron_ingot"), Config::validateItemName);

    static final ForgeConfigSpec SPEC = BUILDER.build();

    public static boolean logDirtBlock;
    public static int magicNumber;
    public static String magicNumberIntroduction;
    public static Set<Item> items;

    private static boolean validateItemName(final Object obj)
    {
        return obj instanceof final String itemName && ForgeRegistries.ITEMS.containsKey(ResourceLocation.tryParse(itemName));
    }

    @SubscribeEvent
    static void onLoad(final ModConfigEvent event)
    {
        logDirtBlock = LOG_DIRT_BLOCK.get();
        magicNumber = MAGIC_NUMBER.get();
        magicNumberIntroduction = MAGIC_NUMBER_INTRODUCTION.get();

        // convert the list of strings into a set of items
        items = ITEM_STRINGS.get().stream()
                .map(itemName -> ForgeRegistries.ITEMS.getValue(ResourceLocation.tryParse(itemName)))
                .collect(Collectors.toSet());
    }
}

I don't touch my config file. Before this it worked but then when i opened Intellij. I changed the version number, as i was working on a new update. It went from 0.1a.0 to 0.1a.1 and then later stopped working.

I tried removing the config file, and then the console also says that i have depreciated gradle features making it not able to run on gradle 9.0?

Heres the gradle.properties folder:

# Sets default memory used for gradle commands. Can be overridden by user or command line properties.
# This is required to provide enough memory for the Minecraft decompilation process.
org.gradle.jvmargs=-Xmx3G
org.gradle.daemon=false
