Bluetooth became unavailable after installing flicd

Hi there!
I am brand new to HomeAssistant. I am discovering how this whole lot works so forgive my maybe silly questions.

I have setup a new HomeAssistant OS on a RPi4 and added my Switchbot Curtains. It worked and I was a happy bunny. Then I installed flick via a repository url. After installing this, my Switchbot curtains became unavailable. I did a reboot of the entire system and now my bluetooth indicates that there was no adapter found.

What happened and what can I do?
