no authentication is provided for private endpoints about bybit.net

I can't reproduce it, the code you posted seems to work for me. Are you sure you're using the same socket client to subscribe as you set the options on? This gives no issues for me:

var bybitSocketClient = new BybitSocketClient(new BybitSocketClientOptions()
{
    AutoReconnect = true,
    UsdPerpetualStreamsOptions = new BybitSocketApiClientOptions()
    {
        ApiCredentials = new CryptoExchange.Net.Authentication.ApiCredentials("KEY", "SECRET")
    },
    InversePerpetualStreamsOptions = new BybitSocketApiClientOptions()
    {
        ApiCredentials = new CryptoExchange.Net.Authentication.ApiCredentials("KEY", "SECRET")
    },
    SpotStreamsOptions = new BybitSocketApiClientOptions()
    {
        ApiCredentials = new CryptoExchange.Net.Authentication.ApiCredentials("KEY", "SECRET")
    },
    InverseFuturesStreamsOptions = new BybitSocketApiClientOptions()
    {
       ApiCredentials = new CryptoExchange.Net.Authentication.ApiCredentials("KEY", "SECRET")
    },
    SocketResponseTimeout = TimeSpan.FromSeconds(10),
    SocketSubscriptionsCombineTarget = 2,
    OutputOriginalData = true,
    LogLevel = Microsoft.Extensions.Logging.LogLevel.Trace,
    ApiCredentials = new CryptoExchange.Net.Authentication.ApiCredentials("KEY", "SECRET")
});

var t = await bybitSocketClient.UsdPerpetualStreams.SubscribeToUserTradeUpdatesAsync(data =>
{
    Console.WriteLine("data");
});

Note that 1 second ResponseTimout might be a bit short

Yes i can confirm that the sameclient is being used also even this reproduces the same error for me:
ApiCredentials apiC = new ApiCredentials(textBox1.Text.Trim(), textBox2.Text.Trim());
bybitSocketClient.ClientOptions.OutputOriginalData = true;
bybitSocketClient.ClientOptions.ApiCredentials = apiC;

        t = await bybitSocketClient.UsdPerpetualStreams.SubscribeToUserTradeUpdatesAsync(OrderHandler);
        if (t.Success)
        {
            Log("[INF]", "Trades monitor started");
        }
        else
        {
            Log("[ERR]", "Socket Error:" + t.Error.Message);
            
        }

is there anything Im missing?permissions of the api key/seceret maybe?

The issue here is that the client options should be set on construction of the client. Setting it after doesn't work correctly.
Setting it like this should work:

var bybitSocketClient = new BybitSocketClient(new Bybit.Net.Objects.BybitSocketClientOptions
{
    LogLevel = LogLevel.Trace,
    ApiCredentials = ApiCredentials(textBox1.Text.Trim(), textBox2.Text.Trim())
});
