CRS 4.0 Bluetooth Dongle stopped working with W10

A few weeks ago, I added a CRS4.0 Bluetooth dongle to my Windows 10 (ver. 1903) desktop PC. It worked & linked up with my Bluetooth headphones. Now, it has stopped working. I've checked in Device Manager & that reports that the Bluetooth driver is there & working OK. On checking for updates, it says I have the best driver for the device. However, if I run the Microsoft Bluetooth Troubleshooter, that reports that my PC does not have Bluetooth & that I should add a Bluetooth Dongle! If I check in Windows Bluetooth settings, the On / Off toggle does not show up. Any ideas how to fix this problem (which I see from the Microsoft Troubleshooter Feedback Hub is quite common) would be much appreciated.

Uninistall the driver.

Restart windows 10 (not shut down) Start - Power - Restart

Reinstall the driver and retry.

Hi 'Fruit Bat /\0/. Thanks for the suggestion. The first time I tried this it didn't fix the problem. I then tried it again and also removed the 'Stack' installed by the CSR4.0 installation CD. After a further re-start it is now working again. It remains to be seen how long for! (Probably only until Microsoft send out the next update.)
