QGIS » QGIS Application

When doing the following commands in the console, my collegue gets the error message below. On my PC, this doesn't happen.
I provide the operating system data of my collegue's PC. Is this a bug? I found something similar, but not 100% the same:
#17600

crsGlobal = QgsCoordinateReferenceSystem(iface.mapCanvas().mapSettings().destinationCrs().postgisSrid())
crsLongLat = QgsCoordinateReferenceSystem(4326)
toGlobal = QgsCoordinateTransform(crsLongLat,crsGlobal)
Traceback (most recent call last):
File "C:\PROGRA~1\QGIS2~1.99\apps\Python36\lib\code.py", line 91, in runcode
