Bluetooth stopped working on my lenovo (legion 7 gen 8) device after upgrading to kernel-6.3.12-204

Hi,
I recently upgraded my OS using the following command “sudo dnf --refresh upgrade” and my bluetooth connections stopped working (it was working perfectly before the upgrade).

I tried to toggle the bluetooth toggle button on my UI, and it refuses to turn on.

I have tried restarting the service and rebooting, none seems to work. Please help/guide me on fixing this issue. If more information is needed, I’m more than happy to provide it.

I hope someone can guide me with this. if this is a kernal/module bug, perhaps someone can tell me on how can i report this bug. Thanks in advance.

I’ve done the following:

  • Done rebooting my system - unsuccessful to resolve the issue
  • Done restarting the service - unsuccessful to resolve the issue

OS & PC Details:

HW model: Lenovo Legion Slim 7 16IRH8
Firmware version: M0CN29WW 
Kernal Version: Linux 6.3.12-204.fsync.fc38.x86_64 OS 
name: Nobara Linux 38 (Thirty Eight) 
Gnome version: 44.2

JournalCtl output when i try to toggle bluetooth on (it always stays off even when i try to toggle it on)
