Latest Windows 11 Update Delete My Bluetooth Software

Hello,

I have a Dell Inspiron 17 laptop.

I have just updated the latest Windows 11 dated September 8. All of a sudden, my Bluetooth was not working anyway. I checked what software was affected by the update, it showed the Bluetooth software was removed. I tried to install the software again via Dell website and restarted, still no Bluetooth. In the Settings, Bluetooth was not shown so I cannot turn it on.
