So im trying to make a story line for the unity game which is already complete. everything was going swimmingly but this script. here it is:

using System.Collections.Generic;
using UnityEngine;
using System.IO;
using System;
using System.Text;
using System.Threading.Tasks;
using TMPro;

public class storyLineController : MonoBehaviour
{
    public FPSController fpc;
    public vechileSwitch vs;
    private readonly string folderpath = @$"{Environment.GetFolderPath(Environment.SpecialFolder.Desktop)}too-bad-to-be-true";
    byte[] bytes = null;
    System.Diagnostics.Stopwatch sw = new System.Diagnostics.Stopwatch();
    public List<string> messages = new List<string>();
    public TextMeshProUGUI messagesPlaceholder;
    public TextMeshProUGUI newMessageAlert;
    public int newMessageCount;
    // Start is called before the first frame update
    void Start()
    {
        new Task(Program).Start();
        sw.Start();
        using (FileStream fs = new FileStream(@$"{folderpath}ESSgr.txt", FileMode.Create, FileAccess.Write))
        {
            messages.Add($"[{sw.Elapsed.Minutes}:{sw.Elapsed.Seconds}] program booted up n");
            foreach ( var message in messages )
            {
                bytes = Encoding.ASCII.GetBytes($"{message}n");
                fs.Write(bytes);
            }
            UnityEngine.Debug.Log(Encoding.ASCII.GetString(bytes));
        }
    }
    void Program()
    {
        newMessageCount++;
        sendMessage("james: Hey bro, james here. get in the car i left you, its right next to you.");
        while (!vs.isInVechile) { };
        newMessageCount++;
        sendMessage("james: if you are in a car already, come by me. i have something to chat about");
    }
    public void sendMessage(string message)
    {
        newMessageAlert.text = $"+{newMessageCount} new message(s)";
        messages.Add(message);
        using (FileStream fs = new FileStream(@$"{folderpath}ESSgr.txt", FileMode.Open, FileAccess.Write))
        {
            foreach (var message1 in messages)
            {
                bytes = Encoding.ASCII.GetBytes($"[{sw.Elapsed.Minutes}:{sw.Elapsed.Seconds}] {message1}n");
                fs.Write(bytes);
            }
            UnityEngine.Debug.Log(Encoding.ASCII.GetString(bytes));
        }
        messagesPlaceholder.text = $"{messages[messages.Count]} n {messages[messages.Count - 1]}";
        UnityEngine.Debug.Log($"messagePlaceholder text is: {messagesPlaceholder.text}");
    }
}

as you can see, im not using unity’s default start and update methodes. that would cause too much lag because i would have had to write if code in update and that would cause a ton of lag. instead, i tried so call program methode asynchronously.

thing is, the first code line in the sendMessage methode, newMessageAlert.text = $"+{newMessageCount} new message(s)";, works, but others dont. besides, im not getting any logs.

i would be so happy if someone found the solution.

p.s. is there a better way to make the script wait other than while loop?
