No connection established IDE 2.3.2 [SOLVED?]

Development Tools IDE 2.x
1

I was trying to compile my code but the No connection established error showed up
It happened after I downloaded the L298N library by Andrea Lombardo
I didn't make changes to the code after i installed the library but i made sure to compile it just in case.
My code:


#define VRX_PIN  A1 // Arduino pin connected to VRX pin
#define VRY_PIN  A2 // Arduino pin connected to VRY pin

#define LEFT_THRESHOLD  500
#define RIGHT_THRESHOLD 530
#define UP_THRESHOLD    500
#define DOWN_THRESHOLD  524

#define COMMAND_NO     0x00
#define COMMAND_LEFT   0x01
#define COMMAND_RIGHT  0x02
#define COMMAND_UP     0x04
#define COMMAND_DOWN   0x08

int xValue = 0 ; // To store value of the X axis
int yValue = 0 ; // To store value of the Y axis
int command = COMMAND_NO;

void setup() {
  Serial.begin(9600) ;
}

void loop() {
  // read analog X and Y analog values
  xValue = analogRead(VRX_PIN);
  yValue = analogRead(VRY_PIN);

  // converts the analog value to commands
  // reset commands
  command = COMMAND_NO;

  // check left/right commands
  if (xValue < LEFT_THRESHOLD)
    command = command | COMMAND_LEFT;
  else if (xValue > RIGHT_THRESHOLD)
    command = command | COMMAND_RIGHT;

  // check up/down commands
  if (yValue < UP_THRESHOLD && yValue > 200)
    command = command | COMMAND_UP;
  else if (yValue > DOWN_THRESHOLD && yValue < 800)
    command = command | COMMAND_DOWN;

  // NOTE: AT A TIME, THERE MAY BE NO COMMAND, ONE COMMAND OR TWO COMMANDS

  // print command to serial and process command
  if (command & COMMAND_LEFT) {
    Serial.println("COMMAND LEFT");
    // TODO: add your task here
  }

  if (command & COMMAND_RIGHT) {
    Serial.println("COMMAND RIGHT");
    // TODO: add your task here
  }

  if (command & COMMAND_UP) {
    Serial.println("COMMAND UP");
    // TODO: add your task here
  }

  if (command & COMMAND_DOWN) {
    Serial.println("COMMAND DOWN");
    // TODO: add your task here
  }
 xValue = analogRead(VRX_PIN);
  yValue = analogRead(VRY_PIN);

  // print data to Serial Monitor on Arduino IDE
  Serial.print("x = ");
  Serial.print(xValue);
  Serial.print(", y = ");
  Serial.println(yValue);

}

Im running Arduino IDE 2.3.2 on windows 10
The board is selected as Arduino Uno on COM3 while i compiled
I also couldn't open the example code from the library

2

What happened when you tried ?

3

nothing happened, no new window or something, nothing happened, i tried multiple times

4

i restarted the IDE and it seems to work fine, i guess i fixed it
