Updated to QtCreator 9.0.0 & now it crashes when I try to open designer

ijststd

Hello
I am new to Qt & QML. I have been using it for just a couple of weeks.

Qt Creator was working fine until I updated to 9.0.0. Now Qt Creator crashes and closes as soon as I press the design button.

I should note that my little app compiles and runs fine in the editor.

So, through the process of elimination have found that this code is what seems to be making it crash.

import QtQuick
import QtQuick.Controls
import QtQuick.Layouts
import QtQml.XmlListModel

Window {
    id: root
    width: 1024
    height: 768
    visible: true
    title: qsTr("Title")

    Component {
        id: compId
        Text {
            id: txtId
        }
    }
}
