CSR Bluetooth Code 43 error

Do you understand the CSR Bluetooth Code 43 error? I got this Bluetooth thingy, the CSR Bluetooth USB 5.0. At first, it worked fine, but then it suddenly stopped after an update. Whenever I plug in the USB, it shows up in the device manager, but then a few seconds later, a warning pops up saying ‘Code 43’. I tried deleting all the drivers, but it didn’t help.

Restart the Bluetooth Support Service:

Press the Windows key (WIN) and R on your keyboard simultaneously. This opens the Run dialog box.
Type in services.msc and press Enter. This opens the Services window.

In the Services window, find the service named “Bluetooth Support Service.”

Restart the Service:

• Right-click on “Bluetooth Support Service.”
