Currently I'm writing an Engine. How I have it right now is that, the engine is written in a project and exports a dll. On another project in the same solution as the engine, there is a sandbox project which uses the engine.

Like this, I write code the engine and sandbox. But there is a bug. The way to produce this bug is that, I run the sandbox project in debug mode with the engine dll. When i spam my mouse and keyboard for a few seconds and close the program via the exit button. The program crashes.

In debug mode. The crash is here:

I found out what produces the bug. Since im currently writing the engine for opengl. I have to use initialize glew and i need to create a HGLRC. So i do that. But this is the issue. If i don't initialize it and try to recreate the bug. Everything is all goochi.

But this can never be the solution since I need to use opengl for my engine. So i went forth and decided to not export the dll from the engine. But instead make the engine an application. So i made a main.cpp and wrote stuff to use the engine. Enabled opengl rendering. Tried to recreate the bug. But everything works!

So at first I thought it might be me being stupid with opengl. But then i found out it works when i make my engine an application. So now i'm thinking it might be my engine.

Has anyone had this issue before ? Or does anyone know why this is happening ? Any solutions ?

Thank you in advance ~

I'm writing an game engine, where the engine is written in a project and exports a .dll file. In another project, in the same solution as the engine, there is a sandbox project which uses the engine. However, there is a bug. 

I run the sandbox project in debug mode with the engine dll. When I spam my mouse and keyboard for a few seconds, and close the program via the exit button, the program crashes with an error:

Exception thrown at 0x00000043 in phantom-sandbox.exe: 0xC0000005: Access violation executing location 0x00000043.

If there is a handler for this exception, the program may be safely continued.

I found the source of the bug. Since I'm currently writing the engine for OpenGL, I have to initialize GLEW, and I need to create a HGLRC. If I don't initialize this HGLRC, everything works.

This is not the ideal solution, since I need to use OpenGL for my engine. I went forth without exporting the .dll from the engine, making the engine an application, instead. I made a main.cpp, and wrote it to use the engine, enabling OpenGL rendering. I tried to recreate the bug, but everything works!

I thought it might OpenGL, but then now I'm thinking it might be my engine. How do I fix this?

Here is my code, where it errors:

    int const main_result = invoke_main()
    
    __telemetry_main_return_trigger(nullptr);
    
    if(!__scrt_is_managed_app())
        exit(main_result)l
        
    if(!has_actor) // < this is the line being sent to the call stack
        _cexit();
        
    __scrt_unititialize_crt(true, false);
    return main_result;
}

__except (_seh_filter_exe(GetExceptionCode(), GetExceptionInformation()))
{
    int const main_result = GetExceptionCode();
    
    if(!__scrt_is_managed_app())
        _exit(main_result);

Here is the call stack:
