I believe I have a similar problem with OpnSense 22.7 (13.1) under LibVirt/QEMU
on a Gigabyte Aorus Motherboard (Gigabyte Technology Co., Ltd. X570 AORUS
MASTER/X570 AORUS MASTER, BIOS F30 09/07/2020)

FreeBSD 13.0-RELEASE works fine, as does OpnSense 22.1 (13.0 also). FreeBSD
13.1-RELEASE crashes in weird ways but OpnSense freezes during kernel init. I
haven't been able to capture a screenshot - it flies by quickly.

The host is a Fedora 36 system.
