PyQt5 script received BEX error in StackHash module

Question

I wrote a script in Python 3.5 using PyQt5 and 2 of my colleagues could not run it - they got an error:

When the script executes the first Qt function:

app = QtWidgets.QApplication(sys.argv)

Answer 1

Unfortunately, I have no errors on my PC, so I could not reproduce. But my colleague found a solution. He needs to clear the import. I originally imported 2 similar packages:

from PyQt5.QtGui import QTextCursor, QFont
from PyQt5.Qt import QTextCursor, QFont

And the problem was fixed when my colleague commented on the second line:

from PyQt5.QtGui import QTextCursor, QFont
#from PyQt5.Qt import QTextCursor, QFont

So, if you ever received a message about a similar error, try clearing your import ...
