Directly opening VM settings to resolve "missing adapter" message after import fails

[ViperPotato]

I'm importing an appliance exported from a Linux host with a host-only network 'vboxnet0' on a Windows 10 host without such a network adapter present.

On powering up, I'm notified about the missing host-only network 'vboxnet0', and I have two options:

1. Change Network Settings
2. Close VM

When I select the first option, the VM settings window opens for a split second before crashing. Powering up the VM again leads to the same behavior.

Opening the VM settings manually, choosing an appropriate host-only network, and saving works around this issue.

This happend after going from 7.0.2 to 7.0.4 and is still present in the current test build 7.0.97.

Log from 7.0.6 attached.
