The error message from pipewire is misleading here; This really means it's
failing to connect to your sessions d-bus service. With the warnings above that
means your session neither set the DISPLAY variable (as used for old-school
autolaunching) nor is the user dbus.socket service enabled/running? Which in
turns points to a setup issue of your user session really.

How is your session started ? can you check the status of your users
dbus.socket?
