Description:
Can't find ESP32 on the Wireless device list using phone or PC.
It happened suddenly while I was testing some code.
There are no error messages. The ESP32 isn't visible anymore.
I've tried:

• resetting by pressing the RST button;

• plugging and unplugging the USB cord;

• uploading the code again.

I also have to mention that I have other ESP32 and they work just fine with the same code and in the same environment.

#include <Arduino.h>

void startAP()
{

  if (SPIFFS.exists("/network.txt"))
    SPIFFS.remove("/network.txt");

  String x = "ESP-";
  x.concat(random(100, 999));
  char ssidAP[x.length() + 1];
  x.toCharArray(ssidAP, sizeof(ssidAP));

  logOutput("Starting AP ... ");
  logOutput(WiFi.softAP(ssidAP, passwordAP) ? (String)ssidAP + " ready" : "WiFi.softAP failed ! (Password must be at least 8 characters long )");
  delay(500);
  logOutput("Setting AP configuration ... ");
  logOutput(WiFi.softAPConfig(local_IP_AP, gatewayAP, subnetAP) ? "Ready" : "Failed!");
  delay(500);
  logOutput("Soft-AP IP address: ");
  logOutput(WiFi.softAPIP().toString());
}

void setup()
{
  if(go_into_station)
  {
     // STA_MODE code
  }
  else
  {
    Serial.println(WiFi.mode(WIFI_AP) ? "Controller went in AP Mode !" : "Controller couldn't go in AP_MODE. AP_STA_MODE 
    will start.");
    startAP();
  }
}

void loop() {
delay(2)
}
