Unsolved Issues with WebView

[Dooham]

Hello,
I was trying to make a really simple web browser with QML, I made the following code:

import QtQuick 2.12
import QtQuick.Controls 2.5
import QtWebView 1.1

ApplicationWindow {
    visible: true
    width: 640
    height: 480
 

    header: ToolBar{
        Row{
            spacing: 6
            ToolButton{
                text: "<-"
                onClicked: {visorWeb.goBack()}

            }
            ToolButton{
                text: "->"
                onClicked: {visorWeb.goForward()}
                }
            ToolButton{
            text: "Reload"
            onClicked: {visorWeb.reload()}
            }
            Label{
            text: visorWeb.loadProgress
            }
            }
        }

        WebView{
            id: visorWeb
            anchors.fill: parent
            url: "https://www.google.es"


        }
    }

With this code I can use the browser, but when I try to load a complex web page (for example "https://www.qt.io") I can see it but I get the following type of errors:
[6932:9236:0607/103211.856:INFO:CONSOLE(84)] "Uncaught TypeError: $(...).carousel is not a function", source: https://www.etsiae.upm.es/fileadmin/html/scripts/upm.js (84)

Does anyone know what I can do to solve this trouble? Thanks

Hi @Dooham

Just tried your code on Ubuntu 16.04 & Qt 5.12.2
url: "https://www.qt.io" works fine.

Which Qt Version & Platform you are using ?

Below links may help you,

QWebEngine asserts with proxy.
Qt: Unknown module(s) in QT: webview.

@Pradeep-P-N Thanks for your response. I am using Qt Creator 4.9.1 in Windows 10. The kit that I used is MSVC2017-64bit.
When you run the code, haven`t you any notice in the application output window?

Hi @Dooham

Below is the Application Output

QML debugging is enabled. Only use this in a safe environment.
WebEngineContext used before QtWebEngine::initialize() or OpenGL context creation failed.

@Pradeep-P-N First of all sorry for my delay. I think the trouble could be with Windows and not with the code. I one of the link that you send me they have a similar trouble and it's just in Windows not in Linux. Maybe it is a problem with the kit that I am using.
