Problems with graph_editor

[JavierDG1996]

When I try to delete a node previously created, with a mouse click, the agent crashes. If you select one or more nodes to delete, they are deleted. It only happens with mouse clicks. This is the error that the console shows when the agent crashes:

Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt.
You must not let any exception whatsoever propagate through Qt code.
If that is not possible, in Qt 5 you must at least reimplement
QCoreApplication::notify() and catch all exceptions there.
