I can't turn on bluetooth. When i open bluetooth settings I get this showing me that bluetooth is turned off:

When I try to turn it on, the switch turns blue, but nothing happens. When I close settings and re-open it, it still shows me that bluetooth is turned off and the switch is turned back off.

I tried using rfkill to unblock it, but when I used `sudo rfkl list` it shows me that bluetooth is neither hard blocked nor soft blocked.

I also tried restarting the driver using

```
sudo rmmod btusb
sudo modprobe btusb

```

and rebooted, but it still didn't work.

It occasionally works when I restart my computer, but sometimes it doesn't even after restarting. How can I fix this issue?
