hey reply guy not sure if you found a fix but I seemed to fix my issue. Im running voidlinux so my installs were a bit different but in the AUR there is a blueman package that contain dependencies you might want to try downloading. My issue on void was not having the gtk+3-devel pacakge installed. might be different for u arch users but try manually installing the dependencies that are listed here https://archlinux.org/packages/extra/x86_64/blueman/
