Hello, i have got the same error by using this in my plugin.

import com.comphenix.protocol.ProtocolLibrary;
import com.comphenix.protocol.ProtocolManager;
import com.comphenix.protocol.events.PacketContainer;
import com.comphenix.protocol.wrappers.WrappedDataWatcher;
//import com.comphenix.protocol.wrappers.WrappedDataWatcherObject;
^ Dosnt exist, i tought it got moved to com.comphenix.protocol.wrappers.WrappedDataWatcher.WrappedDataWatcherObject
import com.comphenix.protocol.wrappers.WrappedChatComponent;
import com.comphenix.protocol.wrappers.WrappedDataWatcher.Registry;
import com.comphenix.protocol.PacketType;
import org.bukkit.Location;
import org.bukkit.entity.Player;

import java.util.UUID;

public class test {
    public void sendInvisibleArmorStand(Player player, Location location, String text) {
        ProtocolManager protocolManager = ProtocolLibrary.getProtocolManager();

        try {
            PacketContainer spawnPacket = protocolManager.createPacket(PacketType.Play.Server.SPAWN_ENTITY);
            int entityId = (int) (Math.random() * Integer.MAX_VALUE);
            spawnPacket.getIntegers().write(0, entityId); // Entity ID
            spawnPacket.getUUIDs().write(0, UUID.randomUUID()); // Unique ID
            spawnPacket.getEntityTypeModifier().write(0, org.bukkit.entity.EntityType.ARMOR_STAND); // ArmorStand Type
            spawnPacket.getDoubles().write(0, location.getX()).write(1, location.getY()).write(2, location.getZ()); // Position

            PacketContainer metadataPacket = protocolManager.createPacket(PacketType.Play.Server.ENTITY_METADATA);
            metadataPacket.getIntegers().write(0, entityId); // Entity ID

            //The Problem I guess:
            WrappedDataWatcher watcher = new WrappedDataWatcher();
            watcher.setObject(new WrappedDataWatcher.WrappedDataWatcherObject(0, Registry.get(Byte.class)), (byte) 0x20); // Invisible
            watcher.setObject(new WrappedDataWatcher.WrappedDataWatcherObject(2, Registry.getChatComponentSerializer(true)), WrappedChatComponent.fromText(text)); // Custom Name
            watcher.setObject(new WrappedDataWatcher.WrappedDataWatcherObject(3, Registry.get(Boolean.class)), true); // Custom Name Visible

            metadataPacket.getWatchableCollectionModifier().write(0, watcher.getWatchableObjects());

            protocolManager.sendServerPacket(player, spawnPacket);
            protocolManager.sendServerPacket(player, metadataPacket);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Server Side Log: https://pastebin.com/NJCEWNMU
Player gets kicked as seen.

The difference for me is that the player only gets kicked when i run this method.

Im Using ProtocolLib 5.4.0-SNAPSHOT-739

Servers Tried:
Paper 1.21.4 (Dev Release)
Spigot 1.21.4

You can use the protocollib jar as an API as a workaround
