networkinformation plugin not available for mingw

I recently installed Qt6.4.3 and I was trying to use QNetworkInformation class. Code didn't worked when building with MinGW but it worked when building same code with MSVC2019. I found out that qnetworkinformation plugin is not available at <QTDIR>\6.4.3\mingw_64\plugins but it is available at <QTDIR>\6.4.3\msvc2019_64\plugins. I reinstalled Qt6.4.3 but it didn't helped. So, it seems qnetworkinformation plugin is missing for MinGW.

// code placeholder
#include <QCoreApplication>
#include<QNetworkInformation>
#include<QDebug>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    qInfo()<<QNetworkInformation::availableBackends();
    qInfo()<<QNetworkInformation::loadDefaultBackend();
    return a.exec();
} 

Output for MinGW build-
