Do you have an Arduino UNO or a fake/copy/clone? Please provide a link to where you purchased it from if online, or a well lit, in focus, close image of the UNO.
I am getting the below error during Upload (simple blink sketch) on Arduino Uno. Please help:
An error occurred while uploading the sketch

Is COM4 indeed your Arduino? Does it disappear from device manager if you disconnect the board?
Did it work before? Or is this the first time that you're working with board.
There might be something with bluetooth, not sure of the details; do a search on the forum and the web.
Please post it; you can't do much wrong but it's just to make sure. Please don't forget code tags as descibed in How to get the best out of this forum.
In that case it is highly unlikely that it would run once.
void setup()
{
pinMode(13, OUTPUT);
}
void loop()
{
digitalWrite(13, HIGH); // Turn on the LED
delay(1000); // Wait for one second
digitalWrite(13, LOW); // Turn off the LED
delay(1000); // Wait for one second
}

Just for the record, I meant to ask if anything was connected to pins 0 and 1 (the Serial) pins. I have the answer, just wanted to make clear what I was asking.
I am unsure whether to call it successful or unsuccessful . As Arduino IDE is throwing out an error (avrdude), but the Arduino board does execute the code once (however does not loop).
I am unsure to call it cross-posting. It is possible the root cause of the two different errors could be same. They might be continent apart too. We can decide once the solution to the second problem (arvdude) is got.
