Good Day JanePilkington1,
I appreciate your time and effort getting back to this thread, what is the exact model of your computer for me to check the Bluetooth driver from the manufacturers website.
For the meantime you can try these steps.
Use the old Bluetooth driver.
-Press Windows key + X
-Go to Device Manager
-Expand the Bluetooth Driver
-Look for Bluetooth driver that was installed
-Right click and Update
-Look for "Browse my computer for driver
-Let me pick drivers available drivers
-Choose an old driver and use it.
-Restart and check.
If issue persist we will download and install the Bluetooth driver from the manufacturers website, let me know what is the exact model.
