Could not fetch native window

[gmyboy]

I am developing with ffplay+SDL2.
this is my code snapshot:

   window = SDL_CreateWindow(program_name, SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED,
                                  default_width, default_height, flags);
        SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "linear");
        if (window) {
            renderer = SDL_CreateRenderer(window, -1,
                                          SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC);
            if (!renderer) {
                av_log(NULL, AV_LOG_WARNING,
                       "Failed to initialize a hardware accelerated renderer: %s\n",
                       SDL_GetError());
                renderer = SDL_CreateRenderer(window, -1, 0);
            }
            if (renderer) {
                if (!SDL_GetRendererInfo(renderer, &renderer_info))
                    av_log(NULL, AV_LOG_VERBOSE, "Initialized %s renderer.\n", renderer_info.name);
            }
        }
        if (!window || !renderer || !renderer_info.num_texture_formats) {
            av_log(NULL, AV_LOG_FATAL, "Failed to create window or renderer: %s", SDL_GetError());
            do_exit(NULL);
        }

Normally, there is no bug. but when user invork this code frequently, sometimes bugs occur:
