how about we try to make module that will update uwpversions?

local UWPVersions = {
    "2.590.678",
    "2.592.586",
}

return UWPVersions
-- MainScript.lua
local UWPVersions = require(script:WaitForChild("UWPVersions"))

game.Players.PlayerAdded:Connect(function(player)
    local success, version = pcall(function()
        return player:GetJoinData().ClientVersionString
    end)
    if success and table.find(UWPVersions, version) then
        player:Kick("UWP detected")
    end
end)
