Serial.println not visible in ide

Software IDE 2.x
1

I'm new to Arduino, so sorry for the basic question but I think I've done all the searching I could at this point. I installed Arduino 2.1 on my Mac, and I'm using it with 'Raspberry pi pico w'.

I can build and upload just fine, but the serial monitor is not available. I get the error "No monitor available for the port protocol serial. Could not connect to /dev/cu.usbmodem14101 serial port."

this is my mildly updated blink sketch.

#include "Adafruit_TinyUSB.h"
#include "hardware/pio.h"


void setup() {
  Serial.begin(115200);
  
  while (!Serial);
  delay(100); 

  Serial.println("Startup");
  pinMode(LED_BUILTIN, OUTPUT);
}


void loop() {
  Serial.println("Looping...");
  digitalWrite(LED_BUILTIN, HIGH); 
  delay(1000);   
  digitalWrite(LED_BUILTIN, LOW); 
  delay(1000); 
}

if I comment out the while loop it starts but without any output. Any advice would be greatly appreciated.
