If it says the scripts directory is missing, it probably means that you need to create a scripts folder.
The steps you've taken:
Fresh installation of Grand Theft Auto V
Downloaded LSPDFR Version 4.3 [2025 Update]
Dragged and dropped all the contents inside the zip folder. (Assuming you did this manually)
Disabled BattleEye in Rockstar Games Launcher
Run the Ragepluginhook exe from the GTA V Directory
