glDrawElements() not working - c++

Question

This has been bothering me for the last days and I can't figure out why.
I know there are a lot of questions like this one here on stackoverflow but none seem to solve my issue.
So here it is the initialization code:
GLuint EBO[1];
GLuint VAO[1];
GLuint VBO[1];
static vec2 tri_pos[8] = {
{-1.0f, -1.0f},
{-1.0f, -1.0f},
{-1.0f, 1.0f},
{-1.0f, 1.0f},
{ 1.0f, -1.0f},
{ 1.0f, -1.0f},
{ 1.0f, 1.0f},
{ 1.0f, 1.0f} };
static GLuint tri_indices[] = { 0, 1, 2 };
glGenBuffers(1, EBO);
glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, EBO[0]);
glBufferData(GL_ELEMENT_ARRAY_BUFFER, sizeof(tri_indices), tri_indices, GL_STATIC_DRAW);
glCreateVertexArrays(1, VAO2);
glBindVertexArray(VAO2[0]);
glCreateBuffers(1, VBO2);
glBindBuffer(GL_VERTEX_ARRAY, VBO2[0]);
glBufferData(GL_ARRAY_BUFFER, sizeof(tri_pos), tri_pos, GL_STATIC_DRAW);
glVertexAttribPointer(4, 2, GL_FLOAT, GL_FALSE, 0, BUFFER_OFFSET(0));
glEnableVertexAttribArray(4);
Here I create the buffers and bind them accordingly. I create the VAO, the VBO and the Element Buffer Object.
Then I assign the tri_pos array to a vec4 in the shader and enable it.
After that I call the draw() function to draw the triangles in this case:
//...
glClearBufferfv(GL_COLOR, 0, cColor);
glBindVertexArray(VAO2[0]);
glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, EBO[0]);
glBindBuffer(GL_VERTEX_ARRAY, VBO2[0]);
glDrawElements(GL_TRIANGLES, 3, GL_UNSIGNED_INT, nullptr);
//glDrawArrays(GL_TRIANGLES, 0, 3);
//glDrawArrays(GL_TRIANGLES, 5, 3);
//glDrawArraysInstanced(GL_TRIANGLES, 0, 3, 1);
//glMultiDrawArrays(GL_TRIANGLES, tri_indices, count, 2);
Here I use glDrawElements() with nullptr because Im using a EBO.
Everything compiles just fine. But at runtime it just crashes. I have no clue what I am missing. All the buffers seem me about right.
Anyone got any clue?

This line is wrong:
glCreateBuffers(1, VAO2);
You are creating a buffer but you probably want to create a vertex array:
glCreateVertexArrays(1, VAO2);
Also replace these calls:
glBindBuffer(GL_VERTEX_ARRAY, VBO2[0]);
with:
glBindBuffer(GL_ARRAY_BUFFER, VBO2[0]);
