You can try downgrading these packages to the previous version.I suspect that is a software error, because BT software was also updated recently.
Later edit: bluez software was updated on December 22nd (security update):
bluez-obexd:amd64 (5.66-1, 5.66-1+deb12u1)
libbluetooth3:amd64 (5.66-1, 5.66-1+deb12u1)
bluez:amd64 (5.66-1, 5.66-1+deb12u1)
The former is the old version, the latter is the new one.
The newer version is due to a security fix:
- Debian Bug report logs - #1057914 bluez: CVE-2023-45866:CVE-2023-45866[0]:
| Bluetooth HID Hosts in BlueZ may permit an unauthenticated
| Peripheral role HID Device to initiate and establish an encrypted
| connection, and accept HID keyboard reports, potentially permitting
| injection of HID messages when no user interaction has occurred in
| the Central role to authorize such access. An example affected
| package is bluez 5.64-0ubuntu1 in Ubuntu 22.04LTS. NOTE: in some
| cases, a CVE-2020-0556 mitigation would have already addressed this
| Bluetooth HID Hosts issue.
