I've tried twice now to upgrade FreeNAS 11.3-U5 to TrueNAS 12.0 to no avail. The boot hangs at "middlewared: loading plugins (pwenc) [4/54]" and if I interrupt this, I see "no such column: system_settings.stg_birthday" in the middlewared.log file. On the chance that this was a one-off problem, I re-ran the upgrade but had the same result.
