QQmlApplicationEngine crashes if Qt6PrintSupport is loaded first.

Hello

I am having problems if I load and unload some Qt Libraries before creating my GUI with QQmlApplicationEngine.

I did an example with LoadLibraryA, but also happens if the loading process is done statically.

int main(int argc, char* argv[])
{ 
    QApplication app(argc, argv); 
    HMODULE hModule = LoadLibraryA("C:\\Qt\\6.5.0\\msvc2019_64\\bin\\Qt6PrintSupportd.dll"); 
    FreeLibrary(hModule); 
    QQmlApplicationEngine engine; 
    engine.load(QUrl(QStringLiteral("Welcome.qml"))); 
    app.exec(); 
}

If I dont call freelibrary, the example runs fine. If i call freelibrary, the app will crash in the last line.

This is my Welcome.qml file

import QtQuick
import QtQuick.Controls

ApplicationWindow { 
    id: mainWindow 
    title: "MyWindow"
    objectName: "mainWindow"
    visible:true
}

I hope it is clear.

Regards

PD 1. If i set the VS2022 to use VS2019 compiler, it happens aswell.

PD 2. It works ok in Qt5
