what method did you use to install it ? was it just sudo apt install virtualbox or did you compile it from source ? – marc-andre benoit Dec 25 '20 at 20:44

This can sometimes happen when the host computer does not cleanly shut down a running VirtualBox instance. It can usually be fixed like this:
- Shut down any VirtualBox VMs that are running
- Close VirtualBox if it's running
- Move a configuration file like this:
mv ~/.config/VirtualBox/VirtualBox.xml ~/.config/VirtualBox/VirtualBox.old - Restart VirtualBox
That should get you running again.
