After the 28.2 update a new error in journal(pipewire)

i just checked the journal log and i have ;
Process 1643 (pipewire-media-) of user 1000 dumped core.
i never had these before and looking at the original post of the mentioned update it seems related to pulse effect,but i don’t have it installed.(i have pipewire installed)

but i never had pulseeffects.

You can disable pipewire if you not use it.

systemctl --user stop pipewire.socket
systemctl --user disable pipewire.socket
systemctl --user mask pipewire.socket

what is it used for?
i read a bit on the Arch wiki and Flatpak audio video is mentionned there;
i use Skype from Flatpak so maybe i need it?
anyhow,this morning after shutting down the PC for the night i didn’t see this error.
