Did you also try "Force DirectX 11" ?
Also do this: backup "dinput8.dll" and delete it from your GTA V directory.
Now you should be able to run GTA V: LSPDFR.
If this did not work, please attach images to your response.
EDIT: Just saw, that you are using ELS and EUP... Those will not work without the newest version of ScriptHookV.
Please uninstall ELS and EUP, if possible. You have to wait till the new versions release date to use ELS and car mod, aswell as uniform mods.
Any data mit the .asi at the end of its name will not be load by RageHookPlugin and will be seen as a data, that shouldnt be there. This occurs the error.
