Virtualbox: cannot create new VMs nor add existing VMs

I want to inform you, that the team of VBox has created a bugfix, which will be integrated in the next minor update of VirtualBox = rel 7.2.0-2

May I remember, that I had put some questions in my posting above, and I hope, that someone will answer?

I am feeling unsafe concerning the use of dkms because it seems to enlarge the complexity of my system and makes it more prone to future instabilities. The tutorial about using dkms here https://forum.manjaro.org/t/root-tip-how-to-kernel-headers-dkms/93840 showing me, that my “feeling of being unsafe” is not fictious.
The best would be, if I could return to regular linux612-virtualbox-host-modules 7.1.12.6 without using kernel headers and dkms but I should be safe, while deinstalling it and installing via pamac. Even tihis could be a risk for my actual well working system.

Could someone please answer?
