Unbound crashes following start

[boneclock]

My Unbound DNS service crashes when my virtual box lan is started when I'm connected to this specific network on my laptop.

10.0.100.1 ---OpnSense with Unbound --- 192.168.1.1

The 10.0.100.0 network is able to resolve the internet when I'm connected to other lans, but there is something odd about this one.  Where should I look?
Thx
