Selecting disabled network interface breaks the app

[Daniel15]

For some reason Winpinator was choosing my WireGuard network interface rather than my local LAN - It showed the VPN IP instead of the local network IP at the bottom right. I changed the network adapter in the settings, but accidentally selected the wrong one. This completely crashed the app, and it wouldn't start up again until I deleted the network interface setting from the registry.

So I guess there's two bug reports here:

1. It shouldn't crash with no error message 😄
2. It should default to physical interfaces before VPN tunnels, as the user most likely wants to transfer a file on their local network
