With the update to
VirtualBox 7.0.2 today, none of my virtual machines would load. Installation of the
VirtualBox 7.0.2 Extension Pack made no difference.
However, once I disabled “3D Acceleration” in the profile of each virtual machine, all of my virtual machines loaded without problem, but, of course, without 3D acceleration.
So, if your virtual machines fail to load, disabling “3D Acceleration” might be the temporary fix you need.
I’m hoping that a future
VirtualBox update soon corrects the problem.
