@Martijnvdlaar Ok... all the files/folders I have marked in yellow on this picture, are not part of a clean GTAV installation. So the first thing you need to do, is make a folder somewhere and move every file/folder marked in yellow, into that new folder. That means that the only things left, are the ones in white.

Once you have done that, run the verification again and then run the game with your now completely clean installation. At this point, don't install any mods of any kind, not even ScriptHookV.

You may have to reinstall your mods and plugins again after this but the simple fact is, until we know a clean install works, chasing mods and plugins is a fruitless task. And as your game doesn't work at all at the moment, you've got nothing to lose.
