ESP32 Debug is OK for simple program but fails for complex program

Hi, i have a strange Debugging problem with Debug ESP32 board, ESP-Prog & PlatformIO.

The wiring are OK and I can debug a simple led program,
when i debug complex program (without to use GPPIO 12,13,14 & 15) the debug fail.
Hardware & platformio.ini are the same
Can you help me?
Thanks

Hardware Wiring
Board: az-delivery-devkit-v4
Board link to usb PC via usb COM9
ESP-Prog link to usb PC via usb COM11
None Vcc link

TEST LED PROGRAM

  1. Power on DevKitC-v4 board via usb
  2. Power on Esp-prog board via usb
  3. Run VSC with PlatformIO
  4. Upload code to DevKiC board
  5. Start Debuggin
  6. Debug is OK

Simple led program

void setup() {
pinMode(2, OUTPUT);
Serial.begin(115200);
while (!Serial);
}
void loop() {
digitalWrite(2, HIGH);
delay(1000);
digitalWrite(2, LOW);
delay(1000);
Serial.print(".");
}

platformio.ino led program
