I fixed it guys! Game is back to normal. All I did was compare the new update.rpf with my older one, and if the size of the files inside the newer rpf were greater than the older one I didnt replace them (Meaning it probably has new content added which is required for game to work) I did something like this, used my brains, and now everything works perfect with 0 crashes!

After the latest gta v update, I can't keep using my previous update.rpf or the game crashes.
If I copy and paste the vanilla update.rpf, the game works fine.
Does anyone know which files I need to replace so that I can keep using the older update.rpf?
Thanks alot!
