TTGO lora32 Guru Meditation Error: Core 1 panic'ed (Interrupt wdt timeout on CPU1)

Question

I'm having problems with the ttglo lora32 oled, I programmed it in Arduino IDE. The code basically does the following; It obtains the temperature and humidity data from a DHT22, displays them on the integrated OLED screen, then, using the JSON library, creates a string with json format and finally sends the string with a serial.Print through the serial port.

Everything works correctly for a few minutes (approximately 15) and then the microcontroller sends the following error through the serial port:

Guru Meditation Error: Core  1 panic'ed (Interrupt wdt timeout on CPU1).

The code is the following:

Adafruit_SSD1306 myDisplay = Adafruit_SSD1306(128,64,&Wire);

int t = 0;
int h = 0;
float tp,hp;

void setup() 
{  
  Serial.begin(9600);
  dht.begin();
  myDisplay.begin(SSD1306_SWITCHCAPVCC, 0x3C);  
  num = 1;
}

void loop() 
{
  
  db = false;
  for(int i = 1; i <= 900; i++) //tiempo en segundos para cada muestra en la base de datos
  { 
    lectura();
    display();
    myDisplay.display();
    delay(1000); 
    json();
  }  
  db = true;
  lectura();
  display();
  myDisplay.display();
  delay(1000);
  json();
  num++;   
}

void lectura ()
{
  hp = dht.readHumidity() * 0.9598 - 4.6208 + 1; 
  tp = dht.readTemperature() * 0.8779 + 1.9411 -1;
  t = ((int)(tp * 10));
  h = ((int)(hp * 10));
}

void display()
{
  myDisplay.clearDisplay();
  myDisplay.setTextColor(WHITE);
  
  myDisplay.setTextSize(2);
  myDisplay.setCursor(0,0);
  myDisplay.print("Temp: ");
  myDisplay.setTextSize(2);
  myDisplay.setCursor(43,16);
  myDisplay.print(tp);
  myDisplay.print(" C");

  myDisplay.setTextSize(2);
  myDisplay.setCursor(0,34);
  myDisplay.print("Hum: ");
  myDisplay.setTextSize(2);
  myDisplay.setCursor(43,50);
  myDisplay.print(hp);
  myDisplay.print(" %");
}
void json ()
{
  StaticJsonDocument<96> doc;
  
    doc["N"] = num;
    doc["Dispositivo"] = "dosificado_2_ss"; 
    doc["Temperatura"] = t;
    doc["humedad"] = h;
    doc["db"] = db;
  
    String output;    
    serializeJson(doc, output);  
    Serial.println(output);   
}

Thanks in advance for the help.
