Anyone here who lately upgraded #Virtualbox from 7.0.2 to 7.0.10 and has lots of "black screens" for Windows 10 virtual machines?
Resize screen -> "black screen"
Boot Windows, login screen loads -> "black screen"

It worked till before the update. I installed the extensions upgrade.

Temporary solution it to safe the state of the vm and start it again, then the screen shows the Windows screen output again.
