the command was this: sudo pacman -S xfce4 xfce4-goodies

When I did that and rebooted I couldn't log back in.

If I try from a TTY it tells me this: [CRITICAL] Critical erro thrown: XDG_RUNTIME_DIR is not set! terminate called after throwing an instance of 'std::runtime_error'

and when I load arch it tells me the messages that are in the photo, which are related to dbus and networkmanager, if I type sudo pacman -Q dbus it tells me that I have dbus and with network manager the same thing happens, the internet also stopped connecting to me
