Help With Error Code

Hello all, new to the arduino world, but have been using for about two months now and I am learning a lot. I came across this problem when uploading a new sketch. I am using LCD Screen with an I2c attachment. I have used the program many times for other projects and this is the first time that this has happened. Not sure what to do.

OS Windows 10 Home 64 bit
Arduino UNO

#include <Wire.h>

void setup() {
  Serial.begin (9600);
 
  // Leonardo: wait for serial port to connect
  while (!Serial) 
    {
    }
 
  Serial.println ();
  Serial.println ("I2C scanner. Scanning ...");
  byte count = 0;
  
  Wire.begin();
  for (byte i = 8; i < 120; i++)
  {
    Wire.beginTransmission (i);
    if (Wire.endTransmission () == 0)
      {
      Serial.print ("Found address: ");
      Serial.print (i, DEC);
      Serial.print (" (0x");
      Serial.print (i, HEX);
      Serial.println (")");
      count++;
      delay (1);  // maybe unneeded?
      } // end of good response
  } // end of for loop
  Serial.println ("Done.");
  Serial.print ("Found ");
  Serial.print (count, DEC);
  Serial.println (" device(s).");
}  // end of setup

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Ok what exactly is the problem? Please define, providing code with no talk of what the problem leads to our inability to help.

The code seems to be compiling fine. The problem is in communication between the PC and the Arduino. Do you have the right com port selected in the Tools menu? Have you tried a different USB cable? Does the USB to serial converter on the Arduino need a driver?

I exited out of the software and turned it back on and that seemed to do the trick. Thanks for reaching out.
