Black ImGui Demo screen and Error Message in MSVC Command Window

[AugustusTurcarum]

Hi everyone,
I am using latest ImGui Docking Branch , GLFW 3.3.8 and GLAD libraries
My System Specifications:
Windows 11
AMD Ryzen 7 6800H with Radeon Graphics
Visual Studio 2022

I am following TheCherno Game Engine Series from his Youtube channel. He is using ImGui and GLFW for the Game Engine HAZEL that he is creating.
I am following the same steps as he progress.However I am experiencing an issue since the Game Engine starts using Docking Branch of ImGui library while he is still running without any issue.
I am getting an Error Display in MSVC Debug command window when I call "ImGui_ImplOpenGL3_NewFrame()" function inside the code below under ImGuiLayer::Begin function !
When I follow the Debug up to the Error Display, it is going through imgui_impl_opengl3.cpp --> ImGui_ImplOpenGL3_CreateDeviceObjects() --> CheckShader() function
Due to this Error message, ImGui::ShowDemoWindow function makes a black Imgui window appear

The link for Cherno's ImGuiLayer.cpp code : https://github.com/TheCherno/Hazel/blob/master/Hazel/src/Hazel/ImGui/ImGuiLayer.cpp

I am still following previous version of his code. It means my ImGuiLayer.cpp file and his is not exactly the same, but the way we call ImGuiLayer::Begin() function is the same.
My following of Cherno's code, a part of ImGuiLayer.cpp is below:

The Error message in MSVC Debug command window is:

It is always activating the error message inside CheckShader() function. I don't know if the reason is AMD Graphic Card or not . I checked FAQ, previous discussions but couln't find the solution.
Can someone help me with the solution for this problem ?
Any help would be much appreciated

Sincerely Yours

The version directive you pass to ImGui_ImplOpenGL3_Init is directly prepended to the internal shaders. As the error states, #version_410 is not a valid GLSL version directive.

Also in the future please ensure you use correct Markdown formatting in your questions, your code is very annoying to read as it is currently written.
