It connected and get IP first but later get IP: 169.254.109.119. This is a complex project, but it working fine on 3.1.0. I don't know if it is relate to ESP IDF 5.4.1 or Arduino ESP32 itself. There are some issue relate like #11294

Sketch

WiFi.begin(ssid.c_str(), pwd.c_str());
  ESP_LOGE(TAG, "Connected to SSID: %s", ssid.c_str());

  wifi_timeout = millis() + 30000;
  while (WiFi.status() != WL_CONNECTED && millis() < wifi_timeout)
  {
    ESP_LOGI(TAG, ".");
    //flashing the blue LED to indicate WiFi connecting...
    ledIndicatorBlink();
  }
  if (WiFi.status() != WL_CONNECTED)
  {
    ESP_LOGI(TAG, "Failed to connect to wifi");
    return false;
  }
  ESP_LOGI(TAG, "Connected to %s", ap_ssid.c_str());
  ESP_LOGI(TAG, "Ready, IP address: ");
  unsigned long dhcpStartTime = millis();
  while ((WiFi.localIP().toString() == "0.0.0.0" || WiFi.localIP().toString() == "") && millis() - dhcpStartTime < 5000)
  {
    ESP_LOGI(TAG, ".");
    delay(500);
  }
  if (WiFi.localIP().toString() == "0.0.0.0" || WiFi.localIP().toString() == "")
  {
    ESP_LOGI(TAG, "Failed to get IP address");
    return false;
  }
  ESP_LOGI(TAG, "%s", WiFi.localIP().toString().c_str());
  ledIndicatorOff();
  // Auto reconnected
  WiFi.setAutoReconnect(true);
  WiFi.persistent(true);

Debug Message

Log above, I use ESP IDF and Arduino as component

Seems there is a missing code. Please provide a minimal compilable example sketch to reproduce
