MCVE Sketch

#include <ESP8266WiFi.h>
#include <ESP8266HTTPClient.h>

char ssid[] = ""; // replace with your ssid & pass
char pass[] = "";

void setup() {

void loop() {
}

delete the library from libraries. it is part of the core package

Hello Juraj. I did what you said and assume that this will work:

`#include <WiFi.h>
#include <WiFiClient.h>
#include <WiFiServer.h>
#include <WiFiUdp.h>

char ssid[] = ""; // replace with your ssid & pass
char pass[] = "";

void setup() {
}

void loop() {
}`

but I get following error:

`C:\Program Files\WindowsApps\ArduinoLLC.ArduinoIDE_1.8.21.0_x86__mdqgnx93n4wtt\libraries\WiFi\src\utility\spi_drv.cpp:21:17: fatal error: SPI.h: No such file or directory

#include <SPI.h>`

and if I add the SPI library>

test2:5:17: error: Please import the SPI library from the Sketch > Import Library menu. As of Arduino 0019, the Ethernet library depends on the SPI library. You appear to be using it or another library that depends on the SPI library.

Now I am little confused as SPI should be present in the core package also right?
I also reinstalled the IDE but it is not helping at all.
The program I pasted in the problem description was working fine a year ago and it is working on my ESP8266 since then.. What am I missing or not understanding?

Update of board helped my to solve the issue. I am sorry for this useless thread.
