Trouble with visual.Window() and LabJackPython

Coding
1

I am writing a code that uses LabJackPython to trigger a stimulus through Psychopy. The code returns the same error every time it is run. The terminal returns this:

2019-07-19 10:50:45.146 Python[43341:436948] ApplePersistenceIgnoreState: Existing state will not be touched. New state will be written to (null)
Traceback (most recent call last):

AttributeError: module 'pyglet.window' has no attribute 'get_platform'

    self.backend.close()  # moved here, dereferencing the window prevents
AttributeError: 'NoneType' object has no attribute 'close'

I believe the problem derives from the visual.Window() as the first error on line 80 is the last line in the visual.Window(). Here is the code for that section:

win = visual.Window(
    size=[1920, 1080], fullscr=True, screen=0,
    allowGUI=True, allowStencil=False,
    monitor='testMonitor', color=[0,0,0], colorSpace='rgb',
    blendMode='avg', useFBO=True,
    units='height')

pyglet is version 1.4.1, Psychopy version 3.1.4, python version 3.7.4.

Thanks in advance for any help.
