I have a Dell T3500 with Ubuntu 22.04 where my Bluetooth won't turn on. I have looked up other questions on this subject but none have quite the same problem I do, namely this error:
"Apr 28 20:45:26 ned-Precision-WorkStation-T3500 bluetoothd[1639]: src/profile.c:register_profile() :1.85 tried to register 00001108-0000-1000-8000-00805f9b34fb which is already regist>

Here's the output of some terminal queries. The daemon seems to be running and the dongle is recognized.
