Bluetooth USB dongle stops working

Hi,

I have Home Assistant running in VirtualBox on Windows 11.

I have a TP-Link USB dongle that is passed through to Home Assistant that I use to control a Switchbot. Recently it would run for a few hours and then stop working with the attached error on the Home assistant command line:

In VirtualBox I can still see the Bluetooth dongle is active and passed through to Home Assistant.
The only way to get it working again is to completely restart the Virtual Machine.

Any assistant would be much appreciated.
