openGL异常闪退

Question

我用visual studio 2022写openGL程序，使用了GLFW和GLEW库。在运行过程中，程序总是在运行一小会儿以后出现异常退出。
报错信息：Exception thrown at 0x79E1A369 (igxelpicd32.dll) in openGL_VS.exe: 0xC0000005: Access violation writing location 0x04AE0000.

#include <GL\glew.h>
#include <GLFW\glfw3.h>

#include <iostream>

using namespace std;
int main(void)
{
    GLFWwindow* window;

    /* Initialize the library GLFW */
    if (!glfwInit())
    {
        cout << "Failed to initialize GLFW" << endl;
        return -1;
    }

    /* Create a windowed mode window and its OpenGL context */
    window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);
    if (!window)
    {
        cout << "Failed to create window using GLFW" << endl;
        glfwTerminate();
        return -1;
    }

    /* Make the window's context current */
    glfwMakeContextCurrent(window);
    
    /* Initialize the library GLEW */
    if (glewInit() != GLEW_OK) {
        cout << "Failed to initialize GLEW" << endl;
        glfwTerminate();
        return -1;
    }

    float vertex[] = {
         0.0f,  0.5f, 0.0f,
        -0.5f, -0.5f, 0.0f,
         0.5f, -0.5f, 0.0f
    };

    unsigned int VAO,VBO;
    glGenVertexArrays(1, &VAO);
    glGenBuffers(1, &VBO);

    glBindVertexArray(VAO);
    glBindBuffer(GL_ARRAY_BUFFER, VBO);

    glBufferData(GL_ARRAY_BUFFER, sizeof(vertex), vertex, GL_STATIC_DRAW);

    glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 3 * sizeof(float)/*Stride*/, (void*)0/*Pointer*/);

    glEnableVertexAttribArray(0);

    glBindBuffer(GL_ARRAY_BUFFER, 0);

    /* Loop until the user closes the window */
    while (!glfwWindowShouldClose(window))
    {
        /* Render here */
        glClear(GL_COLOR_BUFFER_BIT);

        glDrawArrays(GL_TRIANGLES, 0, 3);
 
        /* Swap front and back buffers */
        glfwSwapBuffers(window);

        /* Poll for and process events */
        glfwPollEvents();
    }

    glfwTerminate();
    return 0;
}

异常发生的位置是
glfwSwapBuffers(window);
这句代码

退出之前能够正常绘制图形：

请教一下这是怎么回事？

你这着色器都没写
