Arduino Elegoo code not uploading from certain computers

Development Tools Uploading
1

I have written code for the arduino elegoo robot and it works the way it is supposed to. It uses the IR remote. There are a few buttons with predefined paths and the robot can also be controlled using the directional buttons. There is also a servo motor connected. When I upload the code from my computer to the robot it works but when I copy the code and send it to another student it doesn't work when they upload it. Why would that be?
Here is the code:

#include <IRremote.h>
#include <Servo.h>
int RECV_PIN = 12;
IRrecv irrecv(RECV_PIN);
decode_results results;
#define IR_Go      0x00FF18E7

#define IR_Stop    0x00FF38C7
#define one        0x00FFA25D
#define two        0x00FF629D
#define three      0x00FFE21D
#define four       0x00FF22DD

Doesn't upload or doesn't execute (run)?

It doesn't execute. It says it uploads correctly.

4

Does this just happen with this one robot or other robots too.
