Checklist

I have searched for a similar issue in this repository and did not find one.
I am using an official build obtained from releases or updated one of those builds using its in-app updater.

Describe the Bug

It is no longer possible to launch a game from the command line if using the LauncherQT version. Launch arguments seem to be ignored and don't reach the default selected emulator version, so nothing happens.

This broke integration with game library managers (ex Playnite) which rely on command line use.

Reproduction Steps

Open command line > try to launch a game with -g ImagePath.

Expected Behavior

Launcher passes command to default selected version, which starts as daughter process.

Specify OS Version

Windows 11 25H2

CPU

Ryzen 5600

GPU

RTX 3060

Amount of RAM in GB

24GB

Please run QtLauncher with the -h (or --help) argument and you'll see how to use it properly.

Sorry, it was as easy as adding "-d" to it. My bad. Closing this now.
