Error occurs in the VirtualBox VM installed from the vmdk image when "close" is pressed on the VM window

[Yuri]

I installed this VMDK image 
https://download.freebsd.org/ftp/snapshots/VM-IMAGES/12.0-CURRENT/amd64/Latest/FreeBSD-12.0-CURRENT-amd64.vmdk.xz 
rom Jul 26.

Once it boots, pressing "close" causes the error.
