drivers - Bluetooth "works" but won't pair with headphones. rtl8723de HP laptop

After having gone through the following threads and following the answers:




Wireless was not working: Realtek Semiconductor RTL8723DE Device d723 issue



Bluetooth was not working: How to activate bluetooth device for RTL8723DE? (I am using cosmic but specified the bionic repo to pull down the module)



My bluetooth adapter searches for and finds headphones, but will not connect to them. The adapter will connect to my phone's bluetooth though, so I'm really confused as to what is causing this. I have tried the suggestion here: ubuntu 18.04 bluetooth not set up without any luck. The description of what is happening with my headphones in that post is spot on.



EDIT: I have tried to connect with two different known working headsets.



As I've seen requested in some other posts:
