You are directly or indirectly using either stdout or stderr as an out put for logger but pyinstaller and some or most exe builders produce exes which, when running in Windowed mode, set both of these to None and logger fails like this because None as the exception says doesn’t have an istty or any other methods. Some possible solutions include: * Set the application to be a console application so that it will open a terminal window (it can still use the GUI but log messages will go to the terminal quick but dirty * If the application has the frozen attribute or set sys.stdout is None and no log file is specified then create your logger with the file set to os.devnull this will discard all logs * Use logging.NullHandler<https://docs.python.org/3/library/logging.handlers.html#nullhandler> if frozen or sys.stdout is None. * Always log to a file but please consider using logging.RotatingFileHandler<https://docs.python.org/3/library/logging.handlers.html#rotatingfilehandler> as the default handler if frozen or sys.stdout is None. Hope that this helps.
