I put my fully working SDL game into voids to make it easier to read, but now it just opens up and then closes down instantly.
Here Is My Main.cpp

//Initialize
SDL_Init(SDL_INIT_VIDEO);
int imgflags = IMG_INIT_JPG | IMG_INIT_PNG;
if (IMG_Init(imgflags) != imgflags)
std::cout << "Error" << std::endl;
TTF_Init();

Menu();
Game();
Unload();
return 0;
}

I don't know what that means but you have undefined behavior in your code. I'm not surprised it blows up on you.

You are not supposed to call the destructor of objects. Those destructors are automatically called when the objects are destroyed. If you manually call them, they will be called twice resulting in undefined behavior.

All of those global variables look suspicious, especially since you make no effort to account for errors in initialization.
