You're trying to remove an item which is child of another one, while
QStandardItemModel.takeItem() only works for "root" items.
You need to remove the item's row from the item parent:

        [...]
        delCase01.triggered.connect(lambda: self.delTakeItem(item))
        menu.exec_(self.mapToGlobal(pos))

     def delTakeItem(self, item):
         item.parent().removeRow(item.row())

Cheers,
Maurizio
