Installing packages through apt does not mean they are from Debian.

The steam-launcher package is from https://repo.steampowered.com/steam/
and is maintained by Valve, not by Debian. Please report bugs in it
to <https://github.com/ValveSoftware/steam-for-linux/issues> and not
to Debian.

The closest equivalent package in Debian non-free is named "steam".
Its startup works differently.

You can either install Steam from Valve's packages (the package is named
"steam-launcher"), or remove Valve's apt source
(/etc/apt/sources.list.d/steam.list) and install Steam via Debian
(the packages to install in this case are "steam" and "steam-devices").
Mixing the two does not work.

Please copy and paste the exact text that is shown. Rephrasing it in
your own words results in important information being lost.
