I too, am experiencing this same problem. I usually launch GTAV with steam, but it doesn't fully load. For instance, GTAV will launch, it will start loading through RPH and then after all the plugins I have set to start at that moment are done loading in, boom GTA V has crashed. :/ Not sure what I'm doing wrong. It was just working a few days ago...starting to think it's an issue with one of the cars I was trying to install.
