What I would recommend is installing Gameconfig, Packfile-limit-adjuster, and Heap Adjuster from gta5mods.com
If your game still crashes I suggest changing your mods name to _mods and see if your game loads.
1) if your game does load then delete your mods folder because you installed something that corrupted your folder and you have to rebuild it.
2) if your game still doesnt work then I suggest verifying your game files through your launcher (e.g Steam, Epic, Retail)
Now if your game STILL doesn't work then just reinstall your game...
