VBoxManage commands (as well as GUIs) confirm existence of NAT Network. It was all working until fine with NAT Networks until I upgraded to 7.2.0.

I have since created new VMs, reinstalled VirtualBox, rebooted Mac etc.. to no avail.

How can we reproduce this?

Create a NAT Network. Create any VM that has virtual NIC connected to that NAT Network. When VM start is attempted it will fail.

Did you upload all of your necessary log files, screenshots, etc.?

• Yes, I've uploaded all pertinent files to this issue.
