Most addons related to inventory lists broke because ZOs changed a column's control from "SellPrice" to "SellPriceText".
They moved the original label "SellPrice" to that new name "SellPriceText" and all addons accessing something like label:SetText now break as "SellPrice" is just a container control around that and does not provide that function SetText anymore.
So you can check if the error messages tells you the line and in that line check if there is somehting with "SellPrice" and change it to "SellPriceText" and reload the UI, maybe it fixes it.
If not, wait for official addon updates as often it is "not that simple" unfortunately
