❔ Trying to write to file of a Collatz Conjecture program

hello, complete beginner here. im trying to make a program that takes a random number and puts it through the collatz conjecture, then sends every number used in the collatz conjecture to a .txt file on a USB drive. (quite a mouthful, i know). ive got the part about the collatz conjecture done, but i cant write to a file; i tried using streamwrite and File.WriteAllLines with an array

        static void Main(string[] args)
        {
            Random randgen = new Random();
            UnicodeEncoding encoder = new UnicodeEncoding();

            Console.ReadLine();

        start:

            var values = Array.Empty<string>();

            int selectedNum = randgen.Next();
            int x = selectedNum;

            string localPath = (@"D:\COLLATZ\" + Convert.ToString(x) + ".txt");

            Console.WriteLine("Input: {0}", selectedNum);
                
                while (x > 0)
                {
                    if (x == 1)
                    {
                        break;
                    }
                    if (x % 2 == 0)
                    {
                        x = x / 2;
                        Console.WriteLine("{0} | {1} | {2}", x, "div", Convert.ToString(x % 2));

                    }
                    else
