Hmmm, I don’t know if they’ve changed the API but can you do this in a LocalScript inside StarterPlayerScripts:
local StarterGui = game:GetService("StarterGui")
StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.Screenshot, false)
I’ll definitely be releasing a 1.06 for my DisableCoreGUIFunctions if this is a new feature.
Don’t see the point of this feature anyways, you can do this through the menu already or press Windows + Shift + S.
