ESp032 C6 - Light SleepMode hangs the device?

I amusing the Arduino IDE and I am seeing issue swith typing to use the FireBeetle 2 ESP32-C6 with USB + Light Sleep

ESP connected to computer via USB cable.

#include <esp_wifi.h>

#include "driver/uart.h"

#define TIMER_WAKEUP_TIME_US (2 * 1000 * 1000)

void GoToLightSleep() {

  if (IsSafeToUseSleep()) {

    Serial.println("Going tolight sleep now!");

    // To make sure the complete line is printed before entering sleep mode, need to wait until UART TX FIFO is empty

    uart_wait_tx_idle_polling(CONFIG_ESP_CONSOLE_UART_NUM);

    Serial.println("SLEEP!");

    Serial.flush();

    esp_wifi_stop();

    esp_light_sleep_start();

    esp_wifi_start();

    Serial.println("Wakeup from light sleep now!");

  } else {

    Serial.println("Light sleep mode was supposed to be enabled - but A2 (PIN3) is not held high!");

    delay(1000);

  }

}

void setup() {

  //set the analog resolution to 12 bits (0-4096)66

  // analogReadResolution(12);

  uint64_t err = esp_sleep_enable_timer_wakeup(TIMER_WAKEUP_TIME_US);

  if (err != ESP_OK) {

    Serial.println("Configure timer as wakeup source failed");

  }

  pinMode(LED_BUILTIN, OUTPUT);

  // Start the serial

  Serial.begin(9600);

  delay(500);

}

// THis code checks if it is safe to use sleep mode. Sleep mode will only be enabled if 3.3v is applied to pin 3 (A2) basically via a jumper from the 3.3v rail. This

// will allow us to disconnect the wire incase of bricking the device due to it sleeping to quickly.

bool IsSafeToUseSleep() {

  int A2 = analogRead(3);

  return A2 > 3000;

}

void loop() {

  Serial.println("Loop");

   digitalWrite(LED_BUILTIN, HIGH);  // turn the LED on (HIGH is the voltage level)

  GoToLightSleep();

    digitalWrite(LED_BUILTIN, LOW);   // turn the LED off by making the voltage LOW

  Serial.println("Loop after sleep");

  delay(1000);

}

When I connect a wire from GND to Pin3/A2 the led flashes and USB output continues - no light sleep is enabled when in this configuration.

If I connect 3.3v to Pin3/A2 the led has a single very faint flash and the USB crashes/no longer works. No flashing of the LED after the first inital slight flash. Looks like it is hung.

I do not know what is wrong.  Deep sleep works fine with timer to wake up.
