Here is how I made the AR3012 working again on Windows 10 20H1.

remove AR3012 & its drivers completely from 20H1, later let 20H1 detect it as Generic Bluetooth Radio.
download Qualcomm driver v10.0.1.15 from Microsoft Catalog website, install this driver via driver upgrade.
after v10.0.1.15 being installed, you might see additional device named in "Bluetooth LE" as the one in the Kirill's figure.
try to connect any BT device you couldn't connect after upgrading to 20H1, make sure the AR3012 really WORKS.
then download any Qualcomm driver v10.0.3.x (as Kirill mentioned, the newest one is v10.0.3.22, or let Windows Update do it later), upgrade the driver of AR3012 again with this one.

Notice: NEVER uninstall the v10.0.1.15 while/after upgrading to v10.0.3.x, or the AR3012 will fail again after reboot.

Microsoft Generic Bluetooth Driver -> Qualcomm BT driver v10.0.1.15 -> Qualcomm BT driver v10.0.3.x,

if you did followed the steps, your AR3012 should be working as usual, even after reboot.

Qualcomm Atheros Communications - Bluetooth - 10.0.1.15 (x64)

Qualcomm Atheros Communications - Bluetooth - 10.0.3.22 (x64)

I guess the "Bluetooth LE" is the critical point of this issue.

(I DID hate the crappy W10...... what's M$ doing now? let users recall how windows unstable in 1990s? )

NOTE by MELERIX: by the way, as it is an older driver, it does not support the new Windows 10 shutdown mode called fast startup*, so every time you shut down Windows and then restart it, the device appears with an error, so you have to* disable the fast startup of Windows 10*, in the power options of the control panel.*

I have tried to apply your suggestion and got success until I restart my Lenovo Ideapad s500. So I again searched for the better driver and got the following solution:

https://dlcdnets.asus.com/pub/ASUS/nb/DriversForWin10/Bluetooth/Bluetooth\_QualcommAtheros\_Win10\_64\_VER100322driver\_only.zip.zip

Now download this link and follow the steps below:

Review the InstallStep.txt file to learn how to install the driver.

Step by step
1. Extract the drivers package and get into the folder
2. Click the File option from the upper left corner of the driver package folder
3. Move the cursor to the Open Windows PowerShell option
4. Select Open Windows PowerShell as administrator option
5. Select Yes, Allow this app to make changes to your device.
6. Input .\setup.bat
7. Press Enter key to start drivers installation until return to next command line.
8. After install successfully, please restart.

Do you ever try the clean installation of 10.0.1.15?

As what I said, unistall AR3012 & its drivers completely,

let W10 detect it as Generic BT radio device,

then install 10.0.1.15 again?

If that still doesn't work, try to disable the other Acrop BT devices.

Even if that doesn't work, forget the upgraded W10,

try a clean installation of W10.
