Since buster, gdm3 prefers to use the GNOME Wayland session instead of
any X session (GNOME or otherwise).
If you are consistently using Plasma everywhere, I would suggest
installing KDE's preferred display manager instead of gdm. gdm has a
lot of GNOME assumptions.
There is probably a way to configure gdm to select a Plasma session by
default, but I don't immediately know what it is.
