Please place the following in a file test.py:

import sys
from PyQt6.QtWidgets import QApplication, QMainWindow
from PyQt6.QtWebEngineWidgets import QWebEngineView

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("Hello, World! - PyQtWebEngine")
        self.resize(800, 600)

        # Create a QWebEngineView widget
        self.browser = QWebEngineView()

        # Set the HTML content for the browser
        html_content = """
        <!DOCTYPE html>
        <html>
        <head>
            <title>Hello, World!</title>
        </head>
        <body>
            <h1 style="text-align: center; margin-top: 20%;">Hello, World!</h1>
        </body>
        </html>
        """
        self.browser.setHtml(html_content)

        # Set the browser as the central widget
        self.setCentralWidget(self.browser)

if __name__ == "__main__":
    app = QApplication(sys.argv)
    window = MainWindow()
    window.show()
    sys.exit(app.exec())

Then run it using python.exe inside the venv you created. Do you see “Hello World” there?
