I booted teh media in question on another machine
and did:

# mv /boot/efi/EFI /boot/efi/EFI-disabled

Then I tried booting the Dev Kit machine with
the media connected:

No Synchronous Exception

Eventually it booted to the internal Windows 11 Pro

So it appears that the FreeBSD boot loader is
involved in the problem.


Side note: I've now also tried a USB3-A style port
instead of USB3-C. Both types of ports get the
issue. (Given some Microsft wording I was not sure
that ports USB3-A were involved in potential booting.
They are.)

FYI:

# ls -Tld /boot/efi/EFI/*/*
-r-xr-xr-x  1 root  wheel  865292 Mar 15 21:30:46 2023
/boot/efi/EFI/BOOT/bootaa64.efi
-rwxr-xr-x  1 root  wheel  865292 Mar 15 21:30:46 2023
/boot/efi/EFI/FREEBSD/loader.efi

They still match what is on my normal environment that
still predates the openzfs import disaster.
