There is a later version of this driver, I am not sure what it fixes, but it is probably worth using (I have tested and it works fine).

It can be downloaded from Panasonic's website at https://cpt.pc-dlp.panasonic.co.jp/public/soft_update/d_vuln/wlan/bt_v20_60_0_w81.exe

The MSI can be extracted from the EXE with 7-zip.

Considering that this driver was released in 2018, and all other components of the driver are version 20.60, I am inclined to believe that 18.1.1637.0197 is the final bluetooth audio driver that intel released.

Can you explain the installation process you did? There are a few different exe and batch files, not sure what i´ll need. Also there´s a subfolder but it seems like it will install the intel driver without aptx capabilities.
