Bluetooth not connecting to Samsung Galaxy Buds

[common_sense_me]

I have a Problem with my HP Pavilion DV6 Laptop, which I have upgraded with a Samsung 2TB SSD, on which I clean-installed  Windows 10 Pro (now updated to Version 20H2). I did this mainly because my original harddrive was about to fail, and the Laptops specs are not bad at all (i7 Processor). Everything works fine and super fast now, but i have a problem with the Bluetooth Adapter (Qualcomm Atheros AR3012 Bluetooth 4.0).

The device "USB\VID_0CF3&PID_311D\Alaska_Day_2006" requires further installation (Translation from German).

Beim Start des Geräts USB\VID_0CF3&PID_311D\Alaska_Day_2006 ist ein Problem aufgetreten.

The bluetooth seems to work (i can conntect to a Chromecast Ultra and other devices), but i cannot find my Samsung Galaxy Buds (Version 1) in the device list. This works on my newer Desktop PC.

I cannot figure out how to solve this (after hours of research and multiple delete/reinstall attempts in device manager. Also I cannot find a version of driver, which i can install and will work for Windows 10. I have the driver version 10.0.3.18 installed for the Bluetooth Adapter.

I tryed  Samsungs "Galaxy Buds Manager" and the Windows Store App "Samsung Galaxy Buds Connect" as well as a open source version from XDA. Now I am running out of ideas and  starting to think this might not be possible due to HP not supporting Windows 10 for this Modell Laptop and Qualcomm not making a Driver for this Modell (and/or Windows 10).

Can any one think of a solution to this problem?

I realize this is a older modell of Laptop, but it realy works great now besides this problem.
