Found multiple libraries for "WiFi.h"

[PimPom]

Hi, I have been trying to upload programs to my ESP32 development board. Unfortunately I receive a error message saying Found multiple libraries for "WiFi.h", but if I use an example then it works. I've tried pasting my code in to the example (deleting all the code exept [ include "WiFi.h" ] but then it doesn't work again.

I've tried using the latest version of the arduino IDE (1.8.13) but then I can't upload anything at all to my ESP32. So I use the 1.8.12 version.

1. #include "WiFi.h"
2. #include <ESPmDNS.h>
3. #include <ESPAsyncWebServer.h>
4.  
5. AsyncWebServer server(80); // server port 80
6.  
7. void notFound(AsyncWebServerRequest *request)

18.   Serial.println("softap");
19.   Serial.println("");
20.   Serial.println(WiFi.softAPIP());
21.  
22.  
23.   if (MDNS.begin("Pim")) { // om Pim.local/ in te kunnen geven in de browster
24.     Serial.println("MDNS responder started");

32.   request->send(200, "text/plain", message);
33.   });

The line that says "fatal error" is where your fatal error is located.
