Bluetooth headphones get disconnected with Big Sur

I have Sony WH-CH710N bluetooth headphones that worked fine with Catalina but since updating to Big Sur get disconnected after about 5-10 seconds.

I have tried restarting and factory resetting the headphones
I have reset the bluetooth module
I have deleted bluetooth preferences and restarted my computer (iMac Retina 5K, 27-inch, 2017) several times
I have checked for interfering bluetooth signals and ensured none are present

Does anyone have any suggestions?

iMac 27″ 5K, macOS 11.0

I was able to fix the problem with the following steps:

Open Terminal app
Type in: sudo rm -rf /Library/Audio/Plug-ins/HAL/
Restart your iMac

Hopefully this works for you. It was a huge relief for me.

Glad to hear it! It was a super frustrating problem for me, so when I found the solution (someone else had posted it on a different thread), I was eager to spread the good news. Apple really dropped the ball on this one.
