Virtualbox 7.0.12 VM crashes when a bluetooth component is removed

[louisj]

I recently found an issue on my Ubuntu 18 VM that runs on a Windows 10 host. Each time I disconnect my Bluetooth headset (either by shutting the headset down or disabling the Windows host Bluetooth), the Ubuntu VM instantly crashes. The issue occurs every time I disconnect my Bluetooth headset. I don't get any issue when I connect my Bluetooth headset. The error message states that the memory state can't be read.

This Ubuntu VM is a old set up that I'm keeping (reasonably) up to date. I didn't set anything in particular regarding the audio or in general. The weirdest thing I have is that two vdi are attached.

I can't tell if that issue is new with 7.0.12, as I've been using my Bluetooth headset on a recurrent basis only recently (i.e. after the upgrade to 7.0.12).

The issue disappeared as I updated my Windows host to the latest version (19045.3930) . My guess is that the problem came from a Windows update that was later fixed.
