ESP32 rebooting when I call Server.begin();

[DinuraPasan]

Board Settings

I use Arduino IDE 2.3.3 version

Code

#ifdef ESP8266
#include <ESP8266WiFi.h>
#include <ESP8266mDNS.h>
#elif defined(ESP32)
#include <WiFi.h>
#include <ESPmDNS.h>
#else
#error "Board not found"
#endif

#include <ESPAsyncWebServer.h>

AsyncWebServer Server(80);  // Server port is 80

void notFound(AsyncWebServerRequest *request) {
  request->send(404, "text/plain", "Not found");
}

void setup() {
  Serial.begin(115200);
  WiFi.softAP("ESPAsyncWebServer", "dinura123");
  Serial.println(WiFi.softAPIP());

  if (MDNS.begin("ESP")) {  // esp.local/
    Serial.println("MDNS responder started");
  }

  // Loading home page
  Server.on("/", [](AsyncWebServerRequest *request) {
    String message = "Hello World";
    request->send(200, "text/plain", message);
  });

  // Loading page1
  Server.on("/page1", HTTP_GET, [](AsyncWebServerRequest *request) {
    String message = "This is Page 1";
    request->send(200, "text/plain", message);
  });

  Server.onNotFound(notFound);
  Server.begin();
}

void loop() {}
