C# AES cutting the message in 5 characters

Question

I'm trying to encrypt the string, but it seems to be giving an error in the json, because it's cutting 5 characters from the string.

    public class Test
    {
        public static void Run()

            string encryptedString = "";

            // Create a sample JSON object
            var data = new
                       {
                           name = "Alice",
                           age = 30,
                           email = "alice@example.com"
                       };

            // Serialize the JSON object to a byte array
            var jsonBytes = Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(data));

            // Create an AES encryption algorithm instance
            using (var aes = Aes.Create())

                // Decrypt the remaining bytes in the array
                var decryptedBytes = new byte[encryptedBytes.Length - key.Length - iv.Length];
                using (var decryptor = aes.CreateDecryptor())

                // Convert the decrypted byte array to a string and deserialize the JSON object
                var jsonString = Encoding.UTF8.GetString(decryptedBytes);
                System.Console.WriteLine(jsonString);
