What options did you use to run the command?

the "unrecognized arguments" makes me think you put in an extra switch, or used a switch without the following setting.

usual comman
gallery-dl -A "3" URL

also update:
somehow all python basic command in cmd uses gallery-dl for some reason,

[gallery-dl][debug] Version 1.28.1 - Executable (stable/windows)
[gallery-dl][debug] Python 3.8.10 - Windows-10-10.0.17763
[gallery-dl][debug] requests 2.32.3 - urllib3 2.2.3
[gallery-dl][debug] Configuration Files ['%USERPROFILE%\\gallery-dl.conf']
usage: python.exe [OPTION]... URL...
python.exe: error: The following arguments are required: URL
Use 'gallery-dl --help' to get a list of all options.

im trying run check python command and this i the result

this happen after is uses the update command to update gallery-dl

You've run into the same bug as #6176 and #6560, where gallery-dl replaced your python.exe interpreter with a gallery-dl.exe executable file.

ah i see, so all i need to do is perform reinstallation of my python then?

I'd think so, yes.

And do not attempt to update a pip installed gallery-dl with anything other than pip itself in the future.
