I do have exactly the same problem, neither the LAN works nor the export. A reboot did not solve this. On the Laptop I run Pipewire as well, so it might be related to that. On my workstation with Jack running, I did not had this problem, even though I currently can't test it there because I'm not at home for some days.
For the time being I switched to ALSA and there it works. So it seems to be a problem with Pipewire?
