Error When Trying to use Bluetooth on ESP32

This is the error I got:

E (20801) task_wdt: Task watchdog got triggered. The following tasks did not reset the watchdog in time:
E (20801) task_wdt: - IDLE0 (CPU 0)

This is the code:

/**
 * This example turns the ESP32 into a Bluetooth LE keyboard that writes the words, presses Enter, presses a media key and then Ctrl+Alt+Delete
 */
#include <BleKeyboard.h>

BleKeyboard bleKeyboard;

void setup() {
  Serial.begin(115200);
  Serial.println("Starting BLE work!");
  bleKeyboard.begin();
}

void loop() {
  if(bleKeyboard.isConnected()) {
    Serial.println("Sending 'Hello world'...");
    bleKeyboard.print("Hello world");

    delay(1000);

    Serial.println("Sending Enter key...");
    bleKeyboard.write(KEY_RETURN);

    delay(1000);

    Serial.println("Sending Play/Pause media key...");
    bleKeyboard.write(KEY_MEDIA_PLAY_PAUSE);

    delay(1000);

    Serial.println("Sending Ctrl+Alt+Delete...");
    bleKeyboard.press(KEY_LEFT_CTRL);
    bleKeyboard.press(KEY_LEFT_ALT);
    bleKeyboard.press(KEY_DELETE);
    delay(100);
    bleKeyboard.releaseAll();
  }

  Serial.println("Waiting 5 seconds...");
  delay(5000);
}

What is the decoded debug message when you send the backtrace info to the ESP32 Exception Decoder, look it up on the internet and install it to the Arduino IDE?

I fixed it somehow, when I switched to nano for another project and came back it was working...
