So I found a dll which will unlock everything (I'm done with grinding) and the only problem now is I don't have anything to inject it with.

I have found a post saying you can end battleye in task manager and play things like terrorist hunt, if I were to inject the dll, would it stick after I restart the game or no. (I ask because all it does is unlock every skin and operator, so it probably modifies the save file in some way after the dll is injected so I can actually change the save file.)
