What if you use vfio-pci instead of pci-assign? The BUG happens when the
kernel tries to detach a device from the domain, but the device doesn't
actually belong to a domain. VFIO likely already avoids this because the
bridge and device will both be in the same IOMMU group and therefore attached
to the same domain.
