Must be something screwed up in your mods folder, first make sure you have all of OpenIV's ASIs installed, and try,
heap Adjuster https://www.gta5-mods.com/tools/heap-limit-adjuster-600-mb-of-heap
Gameconfig.xml
And MAYBE Packfile Limit Adjuster https://www.gta5-mods.com/tools/packfile-limit-adjuster
If None Of Those Work Then Backup Your Mods Folder To Your Desktop, And Try To Create A New Fresh Mods Folder, Withouts Mods Then Try Running The Game.
