I had a similar problem. I have been using the same addon DLC pack forever now. With the recent updates, my GTA 5 has been stuck on an infinite loading screen. I tried removing all mods except ScriptHook and a few basics - the game loaded fine. I put back in a portion of my DLC folder - got an infinite loading screen. I tried updating the gameconfig that I had been using, no chance, still didn't work. I just tried using the gameconfig suggested by @Biggdogg which was specifically updated for this past update. That gameconfig fixed it! Thanks Biggdogg! Hope you are able to fix your game too.
