We can infere from the picture that the Bluetooth* adapter is online, but shows error code 28. At this point, the only recommendation we have is to do a clean installation of the driver:
1. Download and save Intel® PROSet/Wireless Software for Bluetooth® technology for Windows® 10, the first option is the one from Dell, or you can also try the one from Intel® Download Center:
Dell Support for XPS 13 9343:
Intel® Wireless Bluetooth® Software for Windows® 10 [19.10.1635]
2. Go to Control Panel, Programs, and uninstall the Intel® Wireless Bluetooth Software.
3. Check Device Manager - Bluetooth, if the Intel® Wireless Bluetooth® driver is installed, proceed to uninstall and delete it.
4. After the Bluetooth software is removed, you can install the driver you downloaded before.
