Update 15.2 to 15.3 Virtualbox Fails to run

The 15.2 was Virtualbox 6.1.22 - the upgrade is 6.1.20 so it is a downgrade

The 15.2 virtualbox-kmp-default were still there for 6.1.22 and 6.1.18

I do not want to build virtualbox the Oracle way

I'm just in the middle of the upgrade and haven't got that far. What happens if you protect your VMs and delete/reinstall VirtualBox?
