What happened?

VirtualBoxVM.exe Application error
The instruction at 0x00007FFFA1534E88 referenced memory at 0x00...001C. The memory could not be read.
Clicking OK terminates Virtual Machine. Without clicking OK the machine works fine. The only problem then is that it hangs up at the very late shutdown process - I guess the powering off.

Classic example of null pointer to some struct/class dereference.

How can we reproduce this?

I have keyboard and mouse and the Yamaha UR242 sound card connected via usb hub. Sound enabled in the VM guest Ubuntu 22.04.
When the hub is powered off (on schedule). The crash happens.
