I encounter "exited with code -1073741819" when installing plugins

[Geoff-Y]

hi sir, i think i need some help
i load my plugins by ctkPluginFrameworkLauncher, the code snippet is as follows:
///////////////////////////////////////////////////////////////////////////////////////////
const QString EVENT_ADMIN_SERVICE = "org.commontk.eventadmin";
void MainWindow::loadPlugins()
{
QDir appDir = QApplication::applicationDirPath();
appDir.cd("plugins");
QString pluginPath = appDir.path();

ctkPluginFrameworkLauncher::addSearchPath(pluginPath);
ctkPluginFrameworkLauncher::start(EVENT_ADMIN_SERVICE);

m_ctkContext = ctkPluginFrameworkLauncher::getPluginContext();

QDirIterator it(pluginPath, QStringList() << "*.dll", QDir::Dirs | QDir::Files | QDir::NoDotAndDotDot, QDirIterator::Subdirectories);
while (it.hasNext())
{
    try
    {            
        QSharedPointer<ctkPlugin> plugin = m_ctkContext->installPlugin(QUrl::fromLocalFile(it.next()));
        plugin->start(ctkPlugin::START_TRANSIENT);

        qDebug() << "plugin name: " << plugin->getSymbolicName() << "\r";
        qDebug() << "plugin version: " << plugin->getVersion() << "\r\n";
    }
	catch (const ctkPluginException& e)
	{
		qDebug() << "error in: " << e.what();
	}
}

}
///////////////////////////////////////////////////////////////////////////////////////////
in most cases, the code work fine(vs2019+Qt5.15), but if i [Rebuild] the solution, it popups the "exited with code -1073741819".
after debugging, i locate the code line:

ctkPluginFrameworkLauncher::start(EVENT_ADMIN_SERVICE);

but bad luck, i don't find problem after reading the source code of the function.
