Client socket being destroyed after unsuccessful read from mqtt_start_receive_schedule() function about esp32-mqtt HOT 2 OPEN

Hello,
Up there, I had kept .lwt_topic = "", BUT when I changed the .lwt_topic = "/lwt" (which is default too)
I got the unauthorization error while subscribing to a topic to MQTT server:

Here are the options I am using:
.client_id = "ESP32_Client", .username = "..............", //I have put it right Adafruit USER .password = ".......................................", //I have put it right Adafruit PASS .clean_session = 0, .keepalive = 120, .lwt_topic = "/lwt", // = "" for disable lwt, will don't care other options previously "/lwt" .lwt_msg = "offlines", .lwt_qos = 0, .lwt_retain = 0, .connected_cb = connected_cb, .disconnected_cb = disconnected_cb, //.reconnect_cb = reconnect_cb, .subscribe_cb = subscribe_cb, .publish_cb = publish_cb, .data_cb = data_cb

I am getting the following UNAUTHORIZED CONNECTION on the log:
