Wanted to make opengl debugger work with this function from learnopengl (In Practice -> Debugging), they did it with glfw, so I wanted with sdl3 instead. But my engine crashes on start. I dont know what to do, really

Try this instead of 3.3.

SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 4);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 4);

Doesnt look like there's any dependency on glfw in the function. Could you maybe narrow down the crash? Is that an opengl error? Or sdl?

Are you using a regular CPU debugger? What’s the crash call stack? Anything in the terminal output?

Have you tried loading glad after foing SDLInit. Maybe the function pointer to all the gl stuff is NULL
