I'm trying to set up perspective projection in OpenGL but it doesn't work

void Camera::setViewportSize(float left, float right, float bottom, float top)
{
    constexpr float fov = glm::radians(45.0f);
    m_projectionMatrix = glm::perspective(fov, (right - left) / (top - bottom), 0.1f, 10.0f);
    recalculateViewMatrix();
}

void Camera::recalculateViewMatrix() 
{
    glm::mat4 translate = glm::translate(glm::mat4(1.0f), glm::vec3(m_position, 0.0f));
    glm::mat4 rotate = glm::rotate(glm::mat4(1.0f), m_rotation, glm::vec3(0.0f, 0.0f, 1.0f));
    glm::mat4 scale = glm::scale(glm::mat4(1.0f), glm::vec3(m_scale, m_scale, 1.0f));

    m_viewMatrix = translate * rotate * scale;
    m_viewMatrix = glm::inverse(m_viewMatrix);

    m_viewProjectionMatrix = m_projectionMatrix * m_viewMatrix;
}

I upload viewProjectionMatrix to shader and use it like this:

gl_Position = u_viewProjectionMatrix * vec4(a_position, 1.0);

It just doesn't show anything. I double checked if I pass good left, right, bottom, top values and it should be all good. Playing with zNear and zFar didn't change anything. Note - When I use ortho, it works like a charm:

    m_projectionMatrix = glm::ortho(left, right, bottom, top, 1.0f, -1.0f);

Update I did add model matrix and I translated it -2 units on z axis. I can see the lines: But they are disorted. They should be (0.0f, 0.0f), (100.0, 100.0) (0.0f, 0.0f), (600.0f, 800.0f) It seem like the centre of screen is at (0, 0)???

They should be at positions:

line1: (0.0f, 0.0f), (100.0, 100.0)
line2: (0.0f, 0.0f), (600.0f, 800.0f)
