Amazon Fire TV stick remote does not automatically reconnect

I am running the latest 109.4 release in my Raspberry Pi 4. Although I have successfully paired my old Amazon Fire TV remote using the Keyboard Remote integration, still it doesn’t reconnect automatically. I need to restart HA every time to reconnect my remote. Any ideas as to how I can solve this?

Here’s how my configuration looks

keyboard_remote:
  device_descriptor: '/dev/input/event0'
  type: 'key_down'

Now it doesn’t seem to connect anymore. I tried with a different bluetooth remote too. Still not working

Here’s what’s happening now after I say connect:
