Thank you Simon for your advice.
I've manually installed the following proposed packages:
* liblzf1_3.6-2~ubuntu1.20.04.1_amd64.deb * virtualbox_6.1.16-dfsg-6~ubuntu1.20.04.1_amd64.deb * virtualbox-dkms_6.1.16-dfsg-6~ubuntu1.20.04.1_amd64.deb * virtualbox-qt_6.1.16-dfsg-6~ubuntu1.20.04.1_amd64.deb
and I can confirm VirtualBox works again under kernel 5.8.0 from Ubuntu 20.04.
