Windows does not log to stdout/stderr when app is launched from a terminal with Console=False

Spec file in question:
https://github.com/Taiko2k/Tauon/blob/9c3658aeb830939cae326ba0b529da4b7362384d/windows.spec

console=False from powershell:

console=True when doubleclicking:

The application is supposed to log to STDOUT and STDERR, but it never does, powershell just instantly returns when launching the app.

The internal logging(which logs both to stderr and the app itself) seems to keep working even when pyinstalled.

What am I doing wrong here?

I would like the app to display stderr when specifically launched from a terminal, but not launch an extra terminal window when EXE is double clicked - is there no way to have my cake and eat it too?

Is there no way to build the application in both modes, and perhaps at least only execute the logging one with some additional -console parameter?

The application is supposed to log to STDOUT and STDERR, but it never does, powershell just instantly returns when launching the app.

Executables built with /SUBSYSTEM:WINDOWED do not have console attached, even if you launch them from console. Similarly, they launch in the background w.r.t. to the console that you launched them from, hence the "instant return".

Is there no way to build the application in both modes, and perhaps at least only execute the logging one with some additional -console parameter?

Short of building two executables - one with console=True and one with console=False (similar to python.exe and pythonw.exe), no. The two modes require two different bootloader executables - one built with /SUBSYSTEM:CONSOLE and one with /SUBSYSTEM:WINDOWED.

Back before Windows Terminal was the default, you could sort of emulate what you want by building a console-enabled application (console=True) and applying --hide-console setting. See https://pyinstaller.org/en/stable/feature-notes.html#automatic-hiding-and-minimization-of-console-window-under-windows, but make sure to read the notes about caveats brought on by Windows Terminal.

That's... disappointing.

Guess I'll just log to file, thank you.
