Hey y'all, I'm having the same issue, with none of the fixes working for me either.
I've reinstalled, repaired, reloaded UI, changed resolution and removed all mods and it's still happening.
Would appreciate any help! Can't use any quest items.
So I don't know if this is a common issue, but is anyone else's backpack kinda buggy? I can't see my quest item section, as it's all greyed out with only a clickable square showing up. And the rest of my backpack tabs are cut off partly by a similar greyed out area.
