If multiple instances launched for Browser application, stucks at :m_profile->settings()->setAttribute(QWebEngineSettings::PluginsEnabled, true);

Sheela

I am using QT 6.6.3 library to build Browser Application:

Browser Application developed from SimpleBrowser sample app:
If I launch single instance of this app by passing url in command line it works fine.

If I launch multiple instances(around 15) with different url's at the same time, Some browser instances get stuck in at statement ```
m_profile->settings()->setAttribute(QWebEngineSettings::PluginsEnabled, true);

in createHiddenWindow() shared below :


BrowserWindow *Browser::createHiddenWindow(const QString pageName, bool offTheRecord)
{
    qInfo("Inside Browser::createHiddenWindow()");

    if (!offTheRecord && !m_profile) {
        //const QString name = u"simplebrowser."_s + QLatin1StringView(qWebEngineChromiumVersion());
        const QString name = pageName;
        m_profile.reset(new QWebEngineProfile(name));
        m_profile->settings()->setAttribute(QWebEngineSettings::PluginsEnabled, true);
        m_profile->settings()->setAttribute(QWebEngineSettings::DnsPrefetchEnabled, true);
        m_profile->settings()->setAttribute(QWebEngineSettings::LocalContentCanAccessRemoteUrls, true);
        m_profile->settings()->setAttribute(QWebEngineSettings::LocalContentCanAccessFileUrls, false);

        QObject::connect(m_profile.get(), &QWebEngineProfile::downloadRequested,
            &m_downloadManagerWidget, [name](QWebEngineDownloadRequest* download) {
                QString path = QStringLiteral("c:\\XXX\\downloads\\");
                path.append(name);
                path.append("\\");
                download->setDownloadDirectory(QFileInfo(path).path());
                download->setDownloadFileName(QFileInfo(path).fileName());
                download->accept();
            });
        /*QObject::connect(m_profile.get(), &QWebEngineProfile::downloadRequested,
                         &m_downloadManagerWidget, &DownloadManagerWidget::downloadRequested);*/
    }
    auto profile = !offTheRecord ? m_profile.get() : QWebEngineProfile::defaultProfile();
    auto mainWindow = new BrowserWindow(this, profile, false);
    m_windows.append(mainWindow);
    QObject::connect(mainWindow, &QObject::destroyed, [this, mainWindow]() {
        m_windows.removeOne(mainWindow);
    });
    return mainWindow;
}

What should be the issue? How to handle this issue?
