today roblox updated like any normal day i go into studio and test run just to remind myself what i got so far but no not this time roblox has decided that my game should just suddenly be broken for no reason so ye here is the error
SetCore: TopbarEnabled has not been registered by the CoreScripts
and here is the code that apparently causes it
game.StarterGui:SetCore("TopbarEnabled", false)
this code can be fixed with a wait before it however doesn't work with loops waiting until there done or anything just waits cause that makes the most sense apparently
idk about the update dude but this will fix it:
local TopBarSuccess while TopBarSuccess ~= true do TopBarSuccess = pcall(game.StarterGui.SetCore, game.StarterGui, "TopbarEnabled", false) wait() end
