Library Error: "Multiple libraries were found for" Error for NodeMCU1.0 ESP-12E module with only used library seen

Question

Here is the Code and the Error message, the code is just a testing file before I work with the code, and when I import just the Keypad.h and Keypad_I2C.h, It worked fine, also work when I only import ESP8266WiFi.h. When I tried only importing one of the Keypad lib and the ESP8266WiFi.h and the error occured.

Code:

#include <Keypad_I2C.h>
#include <Keypad.h>
//#include <ArduinoJson.h>
//#include<SoftwareSerial.h>
#include<ESP8266WiFi.h>
void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

It says error compiling for NodeMCU 1.0 (ESP-12E Module) on the red bar that have "Copy error message" on the right — AOV Ezy, Mar 31 '20 at 21:04

It's a known feature < /sarcasm> since 2017. Include the keypad libs as the last of the standard libs:

//#include <ArduinoJson.h>
//#include<SoftwareSerial.h>
#include<ESP8266WiFi.h>

#include <Keypad_I2C.h>
#include <Keypad.h>

That compiles fine.
And to save you more trouble. Update the ArduinoIDE to 1.8.12 -your version has some features like missing baud selection in serial monitor, not really working tool chain aso.
