Bluetooth cannot detect any device and cannot be detected by other devices

Hello! I have a Dell Vostro 5568 with Intel Killer 1550(AC9260NGW), I installed Manjaro KDE and found that I cannot use bluetooth to connect anything but wireless works fine.

I tried solutions from archwiki and other posts, but seemed to get worse. I’m new to using Linux and don’t know what to do next. Any help would greatly appreciated.

Here’s some information that might help.

$ /usr/lib/bluetooth/bluetoothd -n -d
