How to play online.
How do I play online again after installing mods?
OpenIV>Tools>ASI Manager> Uninstall ASI Loader
Or just use this script . It basically renames your dinput8.dll and scripthookv.dll so you won't have to keep renaming them yourself or uninstalling it from OpenIV, etc. I personally edited the script slightly, so it automatically renames and starts GTA V from steam after renaming the files.
