# systemctl status bluetooth.service

で、

bluetooth.service - Bluetooth service
     Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; vendor>
     Active: active (running) since Mon 2022-01-24 21:15:57 JST; 58min ago
       Docs: man:bluetoothd(8)
[...]

という結果が表示されますか？

　　Active: inactive[...]

という結果が表示されるようでしたら、

# systemctl start bluetooth.service

としてみて、如何でしょうか？
もしかしたら、

　# systemctl start bluetooth.service

の前に

　# systemctl enable bluetooth.service

が必要かも知れません．
