Genymotion unable to start because of VBoxManage error?

I don't know if this question belongs in this community but I hope someone can help.

I installed VirtualBox and Genymotion on Ubuntu 18.04

But, when I run Genymotion it starts to boot and it shows me that it's not able to find VirtualBox, but looking at logs this fails:

Any idea ?
