Bluetooth wont start at Raspberry Pi zero 2

Question

When I run

sudo systemctl status bluetooth.service

it shows loaded but not started. start command wont work. I have to use btusb first.

>>> sudo modprobe btusb
>>> sudo systemctl start bluetooth.service

Also bluetooth icon won't show in panel and when i click Bluetooth Manager it just do nothing.

When I run sudo bluetoothctl is shows

Waiting to connect to bluetoothd...

When I turn bluetooth on by the command above it and try to scan on it says

No default controller available

Bluetooth wont start when I do anything. OS is newly installed and Rasbperry Pi is also relatively new (bluetooth was working fine till now)

UPDATE:

hciuart is also do not working. Here is log
