The current style does not support customization of this control (property: "background"..

[johndummy]

I've a qml code which executes fine when build in QT 6.0.4 but prompt me a runtime error when i build it using QT 6.2.3.

The complete error is the following:
"QML Rectangle: The current style does not support customization of this control (property: "background" item: QQuickRectangle(0x22c49ddefc0, parent=0x0, geometry=0,0 100x40)). Please customize a non-native style (such as Basic, Fusion, Material, etc)"

Here is the portion of code in which the background style is present.

Button {
    id: listen_btn
    text: "Press Me"
    font.pixelSize: 18
    background: Rectangle {
        implicitWidth: 100
        implicitHeight: 40
        border.width: 1
    }

@johndummy from the docs:

Note: The macOS and Windows styles are not suitable for customizing...

As the error message says, you'll need to change your style to something customizable. I do this in main.cpp:

QString styleName = (platform == "android")
                          ? "Material"
                          : (platform == "windows")
                                ? "Universal"
                                : "Fusion";
QQuickStyle::setStyle(styleName);
