After last update no boot

What about that first, then install pipewire

Pipewire-jack and jack2 are in conflict (jack)

This is really strange… pipewire-jack provides everything that your post above shows are dependency issues. At this point I would do this: sudo pacman -Rdd jack2 sudo pacman -Syu As a side note, never use pacman -Syuu(with two "u"s) unless you have a specific reason to. It is safer to use pacman -Syu
