Why does DS18B20 lib hate Serial?

Hi I am trying to read temp from DS18B20 water proof sensor using sample code from https://developer.mbed.org/components/DS1820/

Here is it:

include the mbed library with this snippet

#include "mbed.h"
#include "DS1820.h"
 
DS1820 probe(P0_4);      //BLE Nano Analog Pin
 
Serial  pc(P0_9, P0_11); // tx, rx on ble nano

int main() 
{
    pc.baud(19200);
    while(1) 
    {
        //probe.convertTemperature(true, DS1820::all_devices);         //Start temperature conversion, wait until ready
        //printf("It is %3.1foC\r\n", probe.temperature());
        wait(1);
        
        pc.printf("Hello World\n");
    }
}

If I comment line: DS1820 probe(P0_4); BLE Nano Analog Pin

I can see "Hello World" through USB port, but if I leave it as is "Hello World" is never showed.

What is happening?

Thanks a lot

Alex
