Bluetooth Not Working in UEFI Mode on Ubuntu 22.04

Experiencing issues with the Bluetooth functionality on my Ubuntu 22.04 laptop. Despite trying several solutions, I have not been able to resolve the problem.

Interestingly, the Bluetooth works perfectly when I switch the boot mode to Legacy. However, it fails to work when I switch back to UEFI mode.

Bluetooth status seems running and active.No soft or hard block it seems.But device hciconfig not recognised/loaded."No default controller available" message when scan on command in bluetoothctl is ran.
