ID 413798 - Nuke crashes when closing/clearing specific scripts

Problem summary
Nuke crashes when closing/clearing specific scripts

Customer reported version
Nuke 11.3v3

Customer reported platform
Windows 10

Steps to reproduce

1) In Nuke, open the attached script.

2) Open the Script Editor and run the following command: nuke.scriptClose()

Expected behavior
The script should close without crashing.

Actual behavior
The software will crash after running a nuke.scriptClear(), nuke.scriptClose() or nuke.scriptExit() command in the Script Editor. This also occurs when selecting File>Clear Script or File>Close Comp

Workaround
For nuke.scriptClear() and nuke.scriptClose(), if you call the command using PySide, then crash doesn't happen. This doesn't work for nuke.scriptExit():

from PySide2.QtWidgets import QPushButtonfrom PySide2 import QtCorebutton = QPushButton()button.clicked.connect(nuke.scriptClear)button.animateClick();loop = QtCore.QEventLoop()button.clicked.connect(loop.quit)loop.exec_()

from PySide2.QtCore import QTimerQTimer.singleShot(0, nuke.scriptClose)
