Oh boy, please give your post more structure.
Have you looked at using a custom game config? Things should work fine if you have one.
Here's a good one: Dilapidated's Gameconfig.xml.
If you start getting ERR_FIL_PACK_1 errors you might need to start merging your (vehicle) add-on DLCs.
No, I do never used any gameconfig. When I install anything via OpenIV in update.rpf, game only throws me at desktop with generic "GTA V has stopped working" error, I cannot get pass loading screen with any OpenIV mods... I never encountered issues with any of previous game's versions, only current one (1.0.1365.1) gives me now inability to install any additional custom maps. I just cannot have any add-ons, even after removing ALL addons from dlclist.xml (reverting it to original state without any addons) game will still NOT WORK with ANY edited update.rpf, not even with actual 1.0.1365.1 one! I can run game only with untouched one literally, with ScriptHookV alone and all script mods game still work too, error only appears with mods using OpenIV.asi. Some others are encountering same issue and they also cannot get any OpenIV.asi mods to work in their game, like me... I have no clue whats the hell with this patch - it sounds somehow incompatible with OpenIV.asi...
