My computer’s Bluetooth is not working anymore after doing fresh install of Manjaro 20.1 Mikah. I think this is kernel’s problem as I have tried to downgrade my kernel to Linux 5.4 LTS and the Bluetooth started working.
This is my system information

I am fairly new in Linux world, may be I am doing something wrong.
