How to start threading the function and stop threading by the buttons with Tasks

Question

I'm doing winforms app that can automatically run the Wooting-Double-Movement when Fortnite is running, but I need to thread the function. I can't thread it by System.Threading.Tasks. I tried to use Thread.Start and Thread.Abort but Thread.Abort doesn't work in .NET Core 5.0. So, how can I do this? Button4 is start button and Button5 is stop

using System;
using System.IO;
using System.Threading;
using System.Diagnostics;
using System.Windows.Forms;
using System.Threading.Tasks;

namespace AutoDoubleMovement
{
    public partial class Form1 : Form
    {
        static OpenFileDialog ofd = new OpenFileDialog();

        static Settings Settings = new Settings();
        static Info Info = new Info();

        static string path = $@"C:\Users\{Environment.UserName}\AppData\Local\AutoWDM";
        static string file = $@"{path}\WDM_path.txt";
        static string file_wdm = File.ReadAllText(file);

        // Threading this function
        public static void WDM()
        {
            while (true)
            {
                string wdm_path = File.ReadAllText(file);
                Process[] fortnite = Process.GetProcessesByName("FortniteClient-Win64-Shipping");
                Process[] wdm = Process.GetProcessesByName("wooting-double-movement");
                ProcessStartInfo wdmproc = new ProcessStartInfo() { FileName = wdm_path };

                foreach (Process _wdm in wdm)
                {
                    if (fortnite.Length != 0)
                    {
                        if (wdm.Length == 0)
                        {
                            Process.Start(wdmproc);
                        }
                    }
                    else

                        {
                            _wdm.Kill();
                        }
                    }
                    Thread.Sleep(1000);

Answer 1

1. DO NOT USE static OpenFileDialog ofd = new OpenFileDialog(); Make dialogs only with using () { }
2. Try not Task but normal Thread, with .Start() and .Abort()
