Bluetooth Freeze - Only whilst speaker connected

Hi Forum,
My setup is,
Desktop windows PC
Kickr Core
Wahoo heart monitor
Assioma DUO

And under normal circumstances this has worked flawlessly

The issue appears when I connect either my Bluetooth earbuds or Bluetooth speaker. In either circumstance with 100% repeatability the Bluetooth devices will freeze during the workout, with the earbuds it seems about every 20min but with the speaker it seems every 40min.

Any pointers or suggestions would be very welcome.

Thank you.

Connect your phone to the headphones/speaker!
If you already do that, then look into an aux chord for the speaker.
