OPNsense 26.7 Kernel Panic with Zenarmor 2.6.2

Has anyone seen similar crashes on OPNsense 26.7, particularly when protecting a WireGuard interface with Zenarmor?

Dell OptiPlex 3010
Intel 82575EB NICs (igb)

OPNsense 26.7
FreeBSD 15.1
Zenarmor Engine 2.6.2
Suricata installed

Zenarmor configuration
Routed Mode (L3)
Emulated Netmap Driver
Protected interfaces: igb0 (LAN) and wg1 (WireGuard)

Panic consistently references:
generic_mbuf_dtor()
Fatal trap 12: page fault while in kernel mode

Prior to the panic I see:
generic_mbuf_dtor Error: no netmap adapter on device
generic_netmap_unregister Emulated adapter for igb0 deactivated
generic_netmap_dtor Emulated netmap adapter for igb0 destroyed

For additional testing I'll remove wg1 from Zenarmor protection.
