Error: no matching function for call to 'HardwareSerial::HardwareSerial(int)'

Hello.
I have a Wroom 32 module programming error in the hardwareserial.
can anyone help me please!

ERROR:

Do you have the board type set correctly in the IDE? You should not be pulling from avr/cores.

@mmma88

testGPS.ino.cpp

Is this your sketch name?

[mmma88]

Thank you very much

I did not notice the type of board selected in the ide, the error is gone

But after upload the code , I did not receive anything from the GPS
If you can help me, here is the code:

#include <HardwareSerial.h>
#include <TinyGPS++.h>

HardwareSerial GPSSerial(1);
TinyGPSPlus gps;
String b; 

void setup() {
  Serial.begin(115200);
  GPSSerial.begin(9600,SERIAL_8N1,3,1);
  Serial.println("gps start");
}

void loop() {
  while(GPSSerial.available()>0)
  {
    Serial.println("data received");
    gps.encode(GPSSerial.read());
  }
  if(gps.location.isUpdated()){
    Serial.print("Latitude:");
    Serial.println(gps.location.lat(), 6);
    
    Serial.print("Longitude:");
    Serial.println(gps.location.lng(), 6);
  }
}

I have not used a Wroom 32 or a GPS module so I can't really help there. However, I don't even see the "gps start" message in the serial console so there may be a more fundamental issue going on.
