Set a breakpoint, debug the code step by step, and the program will crash. Commenting out the StopMusicStream function has a greater chance of crashing.

    *pMusic = LoadMusicStream("C:/music.mp3");
    PlayMusicStream(*pMusic);

    UnloadMusicStream(*pMusic);
    delete(pMusic);
    CloseAudioDevice();
    return 0;
}
