I was writing slot function for a button called “pushButton” that I realised the name of the button should actually be “pushButton_AreYouCompany” so I deleted than function and renamed the button and wrote another slot.
Now I get error in this function which is written by Qt

void CompleteUserInfoWindow::qt_static_metacall(QObject *_o, QMetaObject::Call _c, int _id, void **_a)

{

    if (_c == QMetaObject::InvokeMetaMethod) {

        auto *_t = static_cast<CompleteUserInfoWindow *>(_o);

        (void)_t;

        switch (_id) {

        case 0: _t->on_pushButton_Done_clicked(); break;

        case 1: _t->on_pushButton_clicked(); break;

        case 2: _t->on_pushButton_AreYouCompany_clicked(); break;

        default: ;

        }

    }

    (void)_a;

}

enter image description here

Here is compile output:

Any idea how can I fix it?
