Yeah, try all gameconfigs until one works for you. I had to remove my two addon aircraft and use my stock gameconfig for the game to stop freezing on me. I still can't figure it out so no addons for me until then I guess. If you have a modded gameconfig try putting back the vanilla one and removing all addons and see if that helps ya.

Thats strange, I was just using some of the area war muscle cars last night and they didn't dissapear. Peds drive them around and so can i without an issue. Hmm, I wonder what the issue is for you?

So far this has worked for me. Use this trainer..

So far all online dlc vehicles I have driving around the map do not dissapear with this trainer. I'm pretty sure there is a built in "mod" that makes it so dlc cars dont vanish. Give that trainer a shot, see if it works for you. Its an awesome trainer too btw!

@JeffParkerModHDx
Its cool, no worries on a late reply. As soon I was going to do more testing, my game had already updated and now I cant do a test until scripthook comes out. So annoying. I as soon as I have the time and desire to play it, we get "blessed" with a dumb update for dumb online mode. What I dont get is how long are they going to keep updating this game?! How much more dumb crap can R* think of. At this rate I am going to have to buy a harddrive just for GTAV! Annoying..

@Arodriguez253
Alright that's for letting me know for sure, because I have got updates before and the scripthook was still good to go. So they must have changed the update.rpf file in some way. I know the GTAV.exe was updated.

@JeffParkerModHDx
Okay so I did a test finally, I have been busy or else I would have done it sooner. What I did was remove the cfg.dat and pc_settings.bin files so the game could make new ones. I also tried another controller because the one I was using was acting strange because I already fixed it once. Anyways I used my newer controller and did what ya told to with those two files and the game ran quite well. I just took a taxi around the map 4-5 times while I was working out in the garage. I did that for about two hours and I did not crash at all, thank god! I was about to try to complete the Merryweather heist and of course another update from Rockstar and steam auto updated. So now I have to wait for scripthook, a gameconfig and ENT to update to try again. I appreciate the help everyone because I think it was my controller and those two files.

So there is an update? On steam it says my GTAV needs a 64mb update. Damn already?! Time to re-mod all over again..

@JeffParkerModHDx
Ohh okay. I will try that as well! Awesome and thank you for your help! I will let ya know what happens.

@josketer
Hmm..as I look over my PC all that is plugged in the my Microsoft Xbox 360 PC controller. This is what it is exactly..
https://www.amazon.com/Microsoft-Wired-Controller-Windows-Console/dp/B004QRKWLA
Do you think I should unplug it when I launch the game and then plug it back in when the game starts? I have heard of problems like that with other games.

Also I appreciate any help, because this is driving me nuts, lol. Last night I was literally 10 seconds away from completing the Merryweather Heist and then bam, game freezes.

Alright, now its crashing like crazy at the moment.. here what my launcher log says..
