AutoConfig can't read ModifierKeyCode from config

[MrMasrozYTLIVE]

Whenever I try to use ModifierKeyCode(Impl) in my config it just fails to read it:

me.shedaniel.autoconfig.serializer.ConfigSerializer$SerializationException: com.google.gson.JsonIOException: Interfaces can't be instantiated! Register an InstanceCreator or a TypeAdapter for this type. Interface name: java.util.function.Supplier
    at me.shedaniel.autoconfig.serializer.GsonConfigSerializer.deserialize(GsonConfigSerializer.java:83) ~[cloth-config-fabric-15.0.128-fabric.jar:?]
    at me.shedaniel.autoconfig.ConfigManager.load(ConfigManager.java:92) ~[cloth-config-fabric-15.0.128-fabric.jar:?]
    at me.shedaniel.autoconfig.ConfigManager.<init>(ConfigManager.java:53) ~[cloth-config-fabric-15.0.128-fabric.jar:?]
    at me.shedaniel.autoconfig.AutoConfig.register(AutoConfig.java:66) ~[cloth-config-fabric-15.0.128-fabric.jar:?]

It only happens when launched in IDE though

Forgot to mention, this is how I register type:

AutoConfig.getGuiRegistry(ModConfig.class).registerTypeProvider((i18n, field, config, defaults, registry) -> {
            Point point = (Point) config;
            ModifierKeyCodeImpl keyCode = Utils.getUnsafely(field, point, CTPMod.DEFAULT_KEYBIND);

            List<AbstractConfigListEntry> list = new ArrayList<>();
            ConfigEntryBuilder builder = ConfigEntryBuilder.create();
            list.add(builder.startModifierKeyCodeField(Text.translatable(i18n), keyCode)
                    .setModifierSaveConsumer(point::setKeyBind)
                    .setAllowMouse(false)
                    .build());

            return list;
        }, ModifierKeyCodeImpl.class);
