Code compilation error - NodeMCU 1.0 (ESP-12E Module)

[Cerebral_Assassin]

This is my first time working with ESP8266 NodeMCU and I was able to successfully run the Blink program and get the on-board blinking. However, when I try the below sample program I get the error:
Multiple libraries were found for "ESP8266WiFi.h"
Used: C:\Users\XXXXX\Documents\Arduino\libraries\ESP8266WiFi
Not used: C:\Users\XXXXX\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\3.0.1\libraries\ESP8266WiFi
exit status 1
Error compiling for board NodeMCU 1.0 (ESP-12E Module).

Program:

#include <ESP8266WiFi.h>

void setup()
{
  Serial.begin(115200);
  Serial.println();

  WiFi.begin("MY_SSID", "PWD");

  Serial.print("Connecting");
  while (WiFi.status() != WL_CONNECTED)
  {
    delay(500);
    Serial.print(".");
  }
  Serial.println();

  Serial.print("Connected, IP address: ");
  Serial.println(WiFi.localIP());
}

void loop() 
{}

I know a similar topic has been posted multiple times earlier, however I tried most of these steps and still not able to resolve this error. I am using Arduino IDE 1.8.19 with ESP8266 (3.0.1) Board Manager version, and I have this URL (https://arduino.esp8266.com/stable/package_esp8266com_index.json) configured in my preferences for additional boards. Kindly help.

I suggest you remove the version

Used: C:\Users\XXXXX\Documents\Arduino\libraries\ESP8266WiFi

since that does not belong to the core, but maybe to an older version of the ESP core. You should be using the other version.

Thanks. I deleted C:\Users\XXXXX\Documents\Arduino\libraries\ESP8266WiFi but then it started giving some other error. So, I reneamed "C:\Users\XXXXX\AppData\Local\Arduino15" and restarted my Arduino IDE, added the URL for additional board and reinstalled the board manager for ESP8266 and now it can compile.
