InterfaceOptionsFrame_OpenToCategory not working

[Walkerbo]

Hi all

I am having trouble with InterfaceOptionsFrame_OpenToCategory

I have checked the updated InterfaceOptionsFrame.lua and found the open to category function at line 419

I have not been able to get it working at all.

Here is my frame;

local NewbDevBoxInterfaceFrame = CreateFrame("Frame", "NewbDevBoxInterfaceFrame", UIParent, "BackdropTemplate")
NewbDevBoxInterfaceFrame.name = "Newb Dev Box"
NewbDevBoxInterfaceFrame:SetBackdrop(
    {
        bgFile = "Interface\\Buttons\\WHITE8X8",
        insets = {
            left = NumberList.insetSize,
            right = NumberList.insetSize,
            top = NumberList.insetSize,
            bottom = NumberList.insetSize
        },
        tileSize = nil,
        tile = false,
        edgeFile = "Interface\\Tooltips\\UI-Tooltip-Border",
        edgeSize = NumberList.edgeSize
    }
)
NewbDevBoxInterfaceFrame:SetBackdropColor(unpack(TextDimensionList.colourBackdrop))
NewbDevBoxInterfaceFrame:SetBackdropBorderColor(unpack(TextDimensionList.colourBorder))
NewbDevBoxInterfaceFrame:SetScript(
    "OnEvent",
    function(self, event, ...)
        if event == "PLAYER_LOGIN" then -- fires when a player logs in or reloads
            print(TextStringList.addonLoaded) -- Load Message
            initialiseLists()
            setUpNewbDevBoxSortedTable()
            checkOtherAddonsEnabled()
            setCheckBoxesAndButtonFrameMetrics()
            buttonFrameButtonLayout()
        end
    end
)
NewbDevBoxInterfaceFrame:RegisterEvent("PLAYER_LOGIN") -- fires when a player logs in or reloads
NewbDevBoxInterfaceFrame:RegisterEvent("ADDON_LOADED") -- fires when an addon is loaded
InterfaceOptions_AddCategory(NewbDevBoxInterfaceFrame)

My function;

function NEWBDEVBOXTOGGLENEWBDEVBOXINTERFACEFRAME()
    if InterfaceOptionsFrame:IsShown() then
        InterfaceOptionsFrame:Hide()
    else
        InterfaceOptionsFrame_OpenToCategory(NewbDevBoxInterfaceFrame) -- have to do this twice because reasons
        InterfaceOptionsFrame_OpenToCategory(NewbDevBoxInterfaceFrame)
    end
end

And the error;

1x Interface/AddOns/NewbDevBox/NewbDevBox.lua:441: attempt to index global 'InterfaceOptionsFrame' (a nil value)
        [string "@Interface/AddOns/NewbDevBox/NewbDevBox.lua"]:441: in function `NEWBDEVBOXTOGGLENEWBDEVBOXINTERFACEFRAME'
        [string "@Interface/AddOns/NewbDevBox/NewbDevBox.lua"]:1382: in function <Interface/AddOns/NewbDevBox/NewbDevBox.lua:1381>
        
        Locals:
        (*temporary) = nil
        (*temporary) = nil
        (*temporary) = "attempt to index global 'InterfaceOptionsFrame' (a nil value)"
        
 
 
 
        (NewbDevBoxInterfaceFrame)

As you can see the error says that the frame does not exist, yet when I navigate to the addons list I can see and use the category frame without a problem or an error.

I guess something changed with the pre-patch yet I cannot figure out a reason that InterfaceOptionsFrame_OpenToCategory no longer works for me.

Looking for some help with this one.
