I am working on a project in VS with Platformio and C++ which involves connecting an ESP32 to wifi. Suddenly my program stopped connecting to my Wifi. Nothing relevant was altered but suddenly nothing will connect, mystifying! Current program listed below which just tries to make the connection which compiles uploads and runs fine but doesn't connect in the same way nothing else does!...
#include <Arduino.h>
#include <WiFi.h>
// put function declarations here:
#define WIFI_SSID "your SSID"
#define WIFI_PASSWORD "your password"
void setup() {
// put your setup code here, to run once:
Serial.begin(115200);
pinMode(LED_BUILTIN, OUTPUT);
WiFi.begin(WIFI_SSID,WIFI_PASSWORD);
Serial.println("starting");
}
bool isConnected = false;
void loop() {
// put your main code here, to run repeatedly:
if (WiFi.status() == WL_CONNECTED) {
Serial.println("Connected");
digitalWrite(LED_BUILTIN,HIGH);
isConnected = true;
}
if (WiFi.status() != WL_CONNECTED) {
Serial.print(".");
digitalWrite(LED_BUILTIN,digitalRead(LED_BUILTIN));
delay(1000);
isConnected = false;
}
}
Compilation up to upload....

I have tried previous working versions, run them on two different ESP32's pinned earlier versions of ESPidf then explored completely seperate connecting only programs including wifi scanners (it can see the network). Current 'vehicle' is shown below with listing and compilation. I have looked at the router log and can't find any error or indication of a problem anywhere after several days exploring everything I can think of. At a complete loss as to how to proceed, where to look, what to do! Can anyone suggest what might be wrong?
Many thanks in advance
