QGraphicsItem crash

The underlying QGraphicsItem::parentItem will be abnormal:

Custom item inherits QObject and QGraphicsItem After doing a test,

if the item is deleted immediately after sence()>removeItem(), the following abnormal problems may occur(If sence()>removeItem() is normal, there will be no exception.):

I would like to ask if there have been similar problems before, and is there a good solution?
