You need to tell us which addons you got installed at least to narrow it down
I'd start with ESC -> AddOns -> Addons enabled OFF
-> Reloadui with all addons off
Is the error still there, use /bug ingame and report to ZOs.
If no error anymore, it was addon related:
I guess some addon that alters the inventoy, and/or the launde/fence scenes would be the ones that win here.
ZOs changed the "sellPrice" column (or any currency) and thus I think the error comes from that.
So start to disable the ones that got to do with inventory and/or sellPrice or any price additions.
And make sure your go ALL addons updated, and the libraries too!
