OpenGL - Going 3D - c++

Question

I have a script that I am unable to make fully 3D. So far on ortho the background shows up only. In perspective, almost nothing shows up but when I move the camera it does change color.
projection = glm::perspective(glm::radians(44.0f), static_cast<GLfloat>(Width) / static_cast<GLfloat>(Height), 0.1f, 100.0f);
projection = glm::ortho(0.0f, static_cast<GLfloat>(Width), static_cast<GLfloat>(Height), 0.0f, -1.0f, 1.0f);
See below for images:
Image 1:
3D version - Ortho
Image 2:
3D version - Ortho
Image 3:
2D version - Stable and works perfectly
Here is my code that creates and renders sprites:

class Sprite
{
public:
Shader shader;
// Set up Vertex Array Object && Vertex Buffer Object
GLuint VAO,
VBO;
// Constructor
Sprite(Shader &shader){ this->shader = shader; setBuffers(); }
// Deconstructor
~Sprite(){ glDeleteVertexArrays(1, &VAO); }
// Initializes and configures the buffers and vertex attributes
void setBuffers()
{
// Define vertices for the sprite
GLfloat vertices[] = {
// x y z u v

These are the shaders that I am using:
Vertex shader:
#version 440 core
layout (location = 0) in vec3 Position;
layout (location = 1) in vec2 texCoord;
out vec2 TexCoords;
uniform mat4 transformObject;
uniform mat4 view;
uniform mat4 projection;
void main()
{
TexCoords = vec2(texCoord.x, texCoord.y);
gl_Position = projection * view * transformObject * vec4(Position.x, Position.y, Position.z, 1.0);
}
Fragment shader:
#version 440 core
in vec2 TexCoords;
out vec4 colour;
uniform sampler2D tex;
uniform vec3 spriteColour;
void main()
{
colour = vec4(spriteColour, 1.0) * texture(tex, TexCoords);
}
