Debugger times out

Hello all, I am trying to debug a simple hello world app. I am using Visual Studio code with the PlatformIo extension on a 2023 Klai Linux system.
The device is an ESP32S3 with the onboard JTAG port

Enclosed is my platformio.ini file:
[env:esp32-s3-devkitc-1]
platform = espressif32
board = esp32-s3-devkitc-1
framework = arduino
debug_port = /dev/ttyACM0
debug_tool = esp-builtin
upload_port = /dev/ttyACM1

The debugger starts and eventually times out.

Here is the code:
#include <Arduino.h>

void setup() {
// Initialization code (runs once):
Serial.begin(9600); // Initialize communication at 9600 baud
}

void loop() {
// Main code (runs repeatedly):
Serial.println(“Hello, World!”); // Print “Hello, World!” to the Serial Monitor
delay(1000); // Wait for 1 second
}

I have also installed the Platformio core

I can successfully build and flash the code to the device.

Thanks

Joe
