Downgraded Raspbian kernel to d5a7dbe77b71974b9abb133a4b5210a8070c9284 (aka 6.6.51-v8-16k+) and everything is back to normal.

sudo rpi-update d5a7dbe77b71974b9abb133a4b5210a8070c9284

Clearly a recent kernel update bricked Bluetooth.

Just for information, there is a a fix from bluetooth-hci-socket side. See stoprocent/noble#4
