Failed to apply network settings. you might not be able to connect to the Bluetooth network via this machine

I recently upgrade my system from Ubuntu 18.04 to Ubuntu 20.04. In Ubuntu 20.04, I’m unable to connect my Bluetooth headphone with my system (Dell, Inspiron 14, 3000 series). I have also Windows OS where the headphone working properly.

After rebooting the system, I’m getting the following message.
