VirtualBox is version installed from Ubuntu repo:
virtualbox/jammy-updates,now 6.1.50-dfsg-1~ubuntu1.22.04.1 amd64 [installed]
Problem with no longer being able to start any guest OS in VirtualBox first appeared after system update to kernel package:
linux-image-5.15.0-116-generic/jammy-updates,jammy-security,now 5.15.0-116.126 amd64 [installed,automatic]
Choosing to boot using previous kernel package allows VirtualBox to start guest OSs again without issue. Previous kernel package is:
linux-image-5.15.0-113-generic/jammy-updates,jammy-security,now 5.15.0-113.123 amd64 [installed,automatic]
I have the same setup as Andy (comment #22).
