pfSense won’t boot after upgrading from 2.7.2 to 2.8.0.

The upgrade log shows that UEFI boot entry 0002 was marked as active:

Updating boot code...

Marking UEFI boot entry 0002 active
Copying bootx64.efi to /efi/boot on ESP
Unmounting and cleaning up temporary mount point
Finished updating ESP

But that screenshot shows it’s trying and failing to boot 0004. So the first thing I would try is setting 0002 as the active boot value.
