playing MP3 file with QMediaPlayer make program crash

Question

Im playing a mp3 file using QMediaPlayer as a background music for my program. most of times it work without any problem, but in some users system sometimes somehow it make the whole program crash without any message... I generated a dump from user system that have this problem and here is some part of it:

its says that the problem is coming from SMM_MP4Demuxer Module, by looking at its name I think its something that coming from QMediaPlayer... So I wonder how can I manage situation like this..? can I still some how play the sound? or at least can I check if the user system support playing the sound and then play it? and if not just skip it? here is a minimal reproducible of my code (working):

#include <QtWidgets/qapplication.h>
#include <QWidget>
#include <QMediaPlayer>
#include <QMediaPlaylist>
#include <QtWidgets/QHBoxLayout>
#include <QToolButton>
#include <QStyle>

class Widget : public QWidget
{
public:
    explicit Widget(QWidget* parent = Q_NULLPTR)
        : background_sound(new QMediaPlayer(this))
    {
        setupUi();

        QMediaPlaylist* playlist = new QMediaPlaylist(this);
        playlist->addMedia(QUrl("qrc:/background_sound.mp3"));
        playlist->setPlaybackMode(QMediaPlaylist::Loop);

        background_sound->setPlaylist(playlist);
        background_sound->setVolume(70);

        connect(background_sound, &QMediaPlayer::mediaStatusChanged, this, [&](QMediaPlayer::MediaStatus status) {
            if (background_sound->error() == QMediaPlayer::NoError) {
                if (status == QMediaPlayer::LoadedMedia)
                    background_sound->play();
            }
        });

        connect(button, &QToolButton::released, this, [&]() {
            if (background_sound->state() == QMediaPlayer::PlayingState) {
                background_sound->pause();
                button->setIcon(style()->standardIcon(QStyle::SP_MediaStop));
            }
            else if (background_sound->state() == QMediaPlayer::PausedState) {
                background_sound->play();
                button->setIcon(style()->standardIcon(QStyle::SP_MediaPlay));
            }
        });
    }
    ~Widget() = default;

private:
    QMediaPlayer* background_sound;
    QToolButton* button;
    void setupUi()
    {
        setObjectName(QStringLiteral("MainWidget"));
        setWindowTitle(tr("Test QMediaPlayer!"));
        resize(300, 300);

        auto layout = new QHBoxLayout(this);
        layout->setObjectName(QStringLiteral("layout"));

        button = new QToolButton(this);
        button->setObjectName(QStringLiteral("button"));
        button->setMinimumSize(50, 50);
        button->setIcon(style()->standardIcon(QStyle::SP_MediaPlay)); // because we are playing it at start
        layout->addWidget(button);
    }

};

int main(int argc, char* argv[])
{
    QApplication application(argc, argv);
    Widget w;
    w.show();
    return QApplication::exec();
}

if I run the program on for example a sandbox that don't have needed codecs, it will just print errors over and over again infinitely... there is no stop to it... (no crash though) so I wonder how can I make sure if the system actually support playing the sound... and if not try not to play at all...
