Steps to reproduce the issue
Use the previous os + core
Connect the dongle - bluetooth will allow integration and every bt item will be controlled over ble.
Update to current OS & Core.
Bluetooth will fail initialization / setup, after reboot.
From this point, reboots, deletion of bt from Devices & Services, reconnection of the dongle (even to the 2nd usb port), etc., will not revive BT; also, new integration would fail too, with "no unconfigured bluetooth device found".
The System / Gardware / System hardware picture - as above.
