Raspeberry, bluetooth problems after updating os 9.0 core 2022.9.4

i was using os 8.5 and core 2022.8.7 with an asus bt-400. all was working, the bluetooth integration was showing two adapters…

after upgrading only one adapter at the time is visible (hci0) and i lose connection with a switchbot bot that was working perfectly…

tried to revert os and core, problems persists… any non reversible update was added?!?
any idea?! have to reinstall from scratch?! no changes were made to code or configuration…

thanks
