VirtualBox NS_ERROR_FAILURE (0x80004005) macOS

I’m using macOS and installed VirtualBox.

When I start a machine, I’m getting the following error :

Failed to open a session for the virtual machine ubuntu.

The virtual machine 'ubuntu' has terminated unexpectedly during startup with exit code 1 (0x1).

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: MachineWrap
