I had the same issue with Kubuntu 20.04LTS, yesterday and during the installation the bluetooth was working perfectly on my Asus UX305ua than, this morning, no bluetooth adapter found. I solved it by simply plugin in (power supply) my laptop. It appear to be an issue with the power management (energy saving). Something disable the bluetooth adapter to save energy.
So if you have this issue could you try to replicated the issue by
1. pluging the power cord
2. spinning an ubuntu live-cd
This might help the maintainer/developer to help us :)
