Undefined reference error

Hi,
I have a simple program in which I am planning to add data to an SQLite db.
main.qml:

import Felgo 3.0
import QtQuick 2.0
import QtQuick.LocalStorage 2.0
import QtQuick 2.5
//import "ImgCode.js" as ICode

App {

    NavigationStack {

        Page {
            title: qsTr("Using SQLite DB in QML")

            AppButton {
                id: createTable
                text: "Create Table"
                onClicked: ICode.dbInit()
            }

//            AppButton {
//                id: insertToDb
//                text: "Inserting Data"
//                anchors.top: createTable.bottom

//                onClicked: {
//                    //                    var pID = "3"
//                    var pImage = "This is the image. "

//                    ICode.dbInsert(pImage)
//                }
//            }
        }
    }
}

ImgCode.js:

//opening the db or creating it if not exists
function dbInit() {
    var db = LocalStorage.openDatabaseSync("FolkFriends", "1.0",
                                           "The example image storage!",
                                           10000000)

    try {
        db.transaction(function (tx) {
            tx.executeSql(
                        'CREATE TABLE IF NOT EXISTS friends(id INTEGER PRIMARY KEY AUTOINCREMENT, img BLOB)')

            console.log("Table friends is created.")
        })
    } catch (err) {
        console.log("Error creating table in Folkfriends. " + err)
    }
}

//opening db
function dbGetHandle() {
    try {
        var db = LocalStorage.openDatabaseSync("FolkFriends", "1.0",
                                               "The example image storage!",
                                               10000000)
    } catch (err) {
        console.log("Error opening FolkFriends db." + err)
    }
    return db
}

//Adding ID and image code64 to db
//function dbInsert(pImage) {
//    try {
//        var db = dbGetHandle()
//        var rowid = 0
//        pImage = "imagegggggggg"
//        db.transaction(function (tx) {
//            tx.executeSql('INSERT INTO friends (img) VALUES ("oisvu i yid")')
//            var result = tx.executeSql(
//                        'SELECT * FROM friends WHERE ID = (SELECT MAX(ID) FROM friends)')
//            //        console.log("pID: " + pID)
//            console.log("pImage: " + pImage)

//            rowid = result.insertedId
//            console.log("The inserted ID is ", +rowid)
//        })
//    } catch (err) {
//        console.log("Insert error: " + err)
//    }
//}

When I run (or build it) I get the following error message:
system.cpp:-1: error: undefined reference to _imp____acrt_iob_func' system.cpp:-1: error: undefined reference to _imp____acrt_iob_func'
system.cpp:-1: error: undefined reference to _imp____acrt_iob_func' b2Settings.cpp:-1: error: undefined reference to _imp____acrt_iob_func'
I have the same error message with even a brand new QML project so I believe it is something related to Qt.
How can I fix this?
Thank you for help.

@gabor53 Hi,
Your Felgo has no link with your Qt install,AFAIK
Try uninstall/reinstall Felgo. Or send an email to Felgo suport, they will support even if you have free License
