It worked! Thanks.

Hi! Yeah, you should copy them to mods/update/x64/dlcpacks

Turns out it was a combo of my visual settings file bugging out and vehicles.meta being totally screwed up. Thanks for the help!

You probably have a corrupted game file that caused the game to crash in the background, but you wouldn't notice it since the loading screen is still active. 
 
Try to figure out what game file did you change or replace? And replace them with the original files. Especially files contains critical game datas.  

The story doesnt end here, because this game loves screwing me over. I tried to salvage my dlc packs folder by moving it back to gtav/mods/update once i get my new gameconfig and added new vehicle slots, and then it crashes on loading and populating game world😐 i should have never tried to use that longer fist fights mod... root of all my problems.😒

When you put it like that, it's even sadder. 😭

Perhaps you should learn programming in order to write and maintain your own software, for free, to play your game a few days sooner.

You played for around an hour and 20 minutes. That's impressive; remember, GTAV wasn't meant to be modded.
Like I said, that's expected, but maybe try swapping out some plugins to test. I know AmbientAICallouts is quite heavy, so you may want to test without it.
 
Your log is not indicative of anything in particular, but that could be a place to start. 🙂
