Call it with:

public void CreateTelegramThread()
        {
            TelegramBase._needQuit = false;
            TelegramBase.EndLoop = false;
            TelegramBase.alreadyrunning = false;
            TelegramBase.runonce = false;

            TelegramBase._defaultHandler.Load(this);
            // disable TDLib log
            Td.Client.Execute(new TdApi.SetLogVerbosityLevel(0));
            if (Td.Client.Execute(new TdApi.SetLogStream(new TdApi.LogStreamDefault())) is TdApi.Error)
            //if (Td.Client.Execute(new TdApi.SetLogStream(new TdApi.LogStreamFile("tdlib.log", 1 << 27, false))) is TdApi.Error)
            {
                CrossThreadManagement.UpdateRichTextboxText(OutputRT, "error with log stream");
                //throw new System.IO.IOException("Write access to the current directory is required");
                //Console.WriteLine("error with log stream");
            }

            //new Thread(() =>
            //{
            //Thread.CurrentThread.IsBackground = true;
            _ = Task.Run(() => Td.Client.Run());
            //}).Start();

            // create Td.Client
            AuthRequest ar = new();
            TelegramBase.client = TelegramGlobals.CreateTdClient(this, ar);
        }

The crash is actually a false positive because it still runs, works, and even closes the connection properly with the error message up. How can I stop it from popping up after a 2nd run?

A crash can't be "a false positive". You must not call Client.Run() more than once. It is supposed to be called on a dedicated thread, which will handle updates and responses from all TDLib instances.

ok, it appeared that way since it worked every time anyway. I dropped the call down to this and did what you said, no errors now. thanks

public void CreateTelegramThread()
        {
            TelegramBase._needQuit = false;
            TelegramBase.EndLoop = false;
            TelegramBase.alreadyrunning = false;
            TelegramBase.runonce = false;

            // create Td.Client
            AuthRequest ar = new();
            TelegramBase.client = TelegramGlobals.CreateTdClient(this, ar);
        }
