With nothing but carbonite and bug grabber enabled, just get error and it does not bring up map at all:

2x Carbonite/Carbonite.lua:2750: attempt to index local 'map' (a nil value)
[string "@Carbonite/Carbonite.lua"]:2750: in function GetPlyrPos' [string "@Carbonite/Carbonite.lua"]:2622: in function AddInfo'

i just issued fix pull request so hopefully it will be added soon. If you are impatient you can fix it by yourself by modifying NxUI.lua and replacing lines 28 to 51 with this code:

function Nx:UIInit()
    local qc = {}
    self.QualityColors = qc

    for n = 0, 10 do
        local r, g, b, hex = C_Item.GetItemQualityColor(n)
        qc[n] = hex
    end

    qc[1] = "|cffe7e7e7" -- Dim the white

    Nx.Font:Init()
    Nx.Skin:Init()

    Nx.Menu:Init()
    Nx.Window:Init()

    Nx.Button:Init()
    Nx.List:Init()
    Nx.DropDown:Init()
    Nx.ToolBar:Init()

    -- Nx.GList:Init()
end

Chat GPT is awesome :) helped me fixing this with my zero LUA programming knowledge :) and it work perfect :)
BTW your error is second for two carbonite errors showing up and its just because first one (the one i've pushed fix) blocking map from being displayed so carbonite couldn't count player position.

Seems good.
