I run a local server with default settings except that C# is enabled with one script:

using System;
using GTANetworkAPI;

namespace Test {
    public class Main : Script {

        public Main() {

        }

        [ServerEvent(Event.ResourceStart)]
        public void OnResourceStart() {
            NAPI.Util.ConsoleOutput("Test resouce started.");
        }

        [ServerEvent(Event.PlayerDeath)]
        public void OnPlayerDeath(Client client, Client killer, uint reason) {
            client.SendChatMessage("You dided.");
            client.MovePosition(new Vector3(0, 0, 82), 0);
            
        }


        [Command("test")]
        public void test(Client sender) {
            sender.SendChatMessage(sender.Position.ToString());
        }
    }
}

I can connect to the server but as soon as I enter something into the chat (a command for example), the game crashes:

System.AccessViolationException
  HResult=0x80004003
  Message = Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

I'm new to working with ragemp so any help would be appreciated.
