Pipewire seems not to work anymore with my USB camera

I have been using pipewire with my browsers (Firefox v132.0.1 , Chromium v130.0.6723.116 and Vivaldi 7.0.3495.11) for sometime now.
I have 2 webcams. One is built into my laptop lid (which normally stays closed) and one is an external USB one.

Everything has worked fine so far but since a few days only the camera that's built into my laptop lid (which normally stands closed) is recognized by browsers.
I use his website as a test bed.

V4L2 reports both cameras:

$ v4l2-ctl --list-devices; pipewire --version;  wpctl status
WEB CAM: WEB CAM (usb-0000:00:14.0-3.2):
        /dev/video4
        /dev/video5
        /dev/media2

Chicony USB2.0 Camera: Chicony  (usb-0000:00:14.0-7):
        /dev/video0
        /dev/video1
        /dev/video2
        /dev/video3
        /dev/media0
        /dev/media1

So does pw-dump and also wpctl:

$ wpctl status

I have tried to downgrade pipewire packages (libpipewire, pipewire-libcamera, pipewire-session-manager, pipewire) and also reboted by machine several times.
No way.
I had to disable pipewire support into my browsers (ALL OF THEM!) to get the second camera working (through libcamera I presume).
I am discussing the thing with pipewire people, but my idea is that the problem could be unrelated to pipewire. Nor to the browsers.

Any idea?
