Or a third hypothesis: systemd-logind triggers a suspend on lid close if there is no external monitor plugged in. Perhaps it looks for a while too long like there is no monitor, so that systemd-logind suspends the system and the GNOME Shell wayland output object disappears, causing the xwayland error.
