OpenGL rendering Limited to the lower left quarter of the screen

So, I am working on an OpenGL project in C ++ and I am confused with a weird problem where after creating a GLFWwindow and drawing on it, the area I am drawing only includes the bottom left quarter of the screen, For example, if the screen dimensions are 640x480 and I drew a 40x40 (600, 440) square which is displayed here and not in the top right corner as I expected:

If I move the square to an area not within 640x480, it is cropped as shown below:

I'll post my code from main.cpp below:

#define FRAME_CAP 5000.0;

#include <iostream>
#include <GL/glew.h>
#include <GLFW/glfw3.h>
#include "InputHandler.h"
#include "Game.h"
using namespace std;

void gameLoop(GLFWwindow *window){
    InputHandler input = InputHandler(window);

    Game game = Game(input);

    //double frameTime = 1.0 / FRAME_CAP;

    while(!glfwWindowShouldClose(window)){
        GLint windowWidth, windowHeight;
        glfwGetWindowSize(window, &windowWidth, &windowHeight);
        glMatrixMode(GL_PROJECTION);
        glLoadIdentity();
        glOrtho(0.0, windowWidth, 0.0, windowHeight, -1.0, 1.0);
        glMatrixMode(GL_MODELVIEW);
        glLoadIdentity();
        glViewport(0, 0, windowWidth, windowHeight);

        game.render();
        game.handleInput();
        game.update();

        glfwSwapBuffers(window);
        glfwPollEvents();

    }

}

int main(int argc, const char * argv[]){
    GLFWwindow *window;

    if(!glfwInit()){
        return -1;
    }

    window = glfwCreateWindow(640.0, 480.0, "OpenGL Base Project", NULL, NULL);

    if(!window){
        glfwTerminate();
        exit(EXIT_FAILURE);
    }

    glewInit();

    glfwMakeContextCurrent(window);

    gameLoop(window);

    glfwTerminate();
    exit(EXIT_SUCCESS);
}

      

        
        
        
      

    

I'm not sure why this will happen, but if you have any ideas, let me know, thanks!
