Did you check in the system manufacturer’s website for BIOS updates that may fix the issue?
Was it a clean or upgrade operating system installation?
Perhaps a system refresh helps. How to refresh, reset, or restore your PC - Windows Help
I suppose that, from your first post, you upgraded your computer from a mechanical drive probably to the SSD. I guess the older drive still has an operating system installed, and if you swapped it in you can see if you have Bluetooth capabilities, and therefore discarding or proving a hardware problem.
