[SOLVED] Can't use --noconsole of Pyinstaller without crash

Can't use --noconsole of Pyinstaller without crash

I have a little problem. When I run my python code, everything works, and with pyinstaller when I compile it with the console. But when I compile it without console with pyinstaller, it crashes. Do you have an idea ?

My program uses the yt_dlp and pyqt5 libraries. It's a graphical interface that allows to download all kind of videos.

My repo : https://github.com/Blackfireoff/VOD_Downloader

I tried to remove all prints and set the output of yt_dlp to "quiet" so that there are no logs in the console, but this did not change anything.

Solution

Add this code before you start QApplication to fix it:

# Add this
if sys.stderr is None:
    stream = io.StringIO()
    sys.stdout = stream
    sys.stderr = stream

app = QApplication(argv, APP_NAME)

I struggled with this bug before. After I go into the code where the bug happened, I found out that this bug caused because sys.stderr is None. Therefore, it will throw NoneTypeException (I don't remember what is this exception called).
