There is no problem with PulseAudio. No matter if a user was using PulseAudio or PipeWire by default, some packages require pipewire-session-manager. Both wireplumber and pipewire-media-session provide pipewire-session-manager. Since wireplumber 0.4.10-2 replaced pipewire-media-session, everyone with a package requiring pipewire-session-manager was affected.
