Titan Ascendancy Extra inventory chest unable to open

Good evening all, have encountered a bug on PS5 where I am unable to access my Titan ascendancy extra inventory chest completely! I highlight the toggle to show the extra inventory, press the activation button, and yet, no inventory. I have tried restarting the game, nothing, I tried refunding the skill points and for some reason am unable (may have something to do with items in that inventory), have tried even going as far as turning off item snapping, but nothing.
