ok, after testing the issue appears to be closing the window after creating an item.
I was able to create several items but as soon as i tried to close the window it crashed.
I'll start researching this further.
Until i am able to resolve the issue, I will update mine with the default.
That's probably the easiest way around it for now.
And in all honesty, you may like their new version better than my old version.
It's been updated to include everything that made me edit it in the first place except recipe browsing while crafting.
P.S.
Same goes for the persona window regarding factions for now.
