Hey Mike thanks for waiting - the version on title screen and ps5 home screen is ok, it shouldn't have any impact on your game
As for the original issue for the "Laid Bare" achievement - the dev team have investigated and done everything they can to find out what is causing the issue for you, and unfortunately there is nothing further the team can do : (
From their end, the devs have been able to on fresh play throughs, and using save data files - it all comes back as being able to progress with giving Nhero the unburdened shield.
This is the step by step message I got from the devs investigating this for you:
I played naturally, doing all quests, Nhero, Shopkeeper and the blacksmith, I have only remembered the Serrated Sword and the hammer, and then have proceeded through each section until you meet Hoover in The Vault, there I talked to him and unburdened the Shield of Inspiration, I then backtracked to Festivity Row where I talked to Nhero and offered him the Unburdened Shield of Inspiration, at this point it should be called Unburdened, and he took it without issue. I even tested the same situation with "Unburdened" in NG+ this morning and had no issues.
I'm really sorry, it looks like we may not have a fix for this issue you have encountered, this is not the outcome any of us wanted!
