New to Qt and having issues updating an old application

[Colin_X1]

Getting the following error:

QQmlApplicationEngine failed to load component
qrc:/main.qml:44:1: module "QtQuick.Controls.Styles" is not installed
Error: Your root item has to be a Window.
QML debugging is enabled. Only use this in a safe environment.
15:39:47: C:\Users\PlummerC\Desktop\EKC\build-ekc-Desktop_Qt_6_5_3_MinGW_64_bit-Debug\debug\ekc.exe exited with code -1

The application was developed a few years ago and was working. The error is probably due to changes needed due tho version changes of Qt.

@Colin_X1 Styles are for Qt Quick Controls 1.0 which are not supported anymore I think. You need to port to Qt Quick Controls 2 or use some older Qt version.
