@stephenw10 Not too sure but when I would reboot while in CE, I'd get stuck on the message OP posted but after a couple of reboots I was able to load and update to pfSense Plus. Which in turn, looking at the upgrade process, downloaded amd64 files and prevent the hang up on that screen.
I'll see if I can replicate when 24.03 releases. I like to do a clean install from CE to pfSense Plus when a major release comes out.
Since OP said that he was able to boot after a few reboots, what can cause the issue? At first I thought it was due to running pfSense in Proxmox but it even happened on bare metal.
