okay so just like everyone else i was crashing and getting error 16... i got the bypass and all that and the game was coming to i was like oh sweet im getting somewhere... but id still crash while loading the game. which i understood to be normal.
so i made sure i had updated files and downloaded the new scripthook V and i still crashed.
i was like okay imma try something. so i pulled out all my scripts to try 1 by 1... still crash.
okay threw them back in... pulled out the mods folder.... BAM game loaded.
from there i threw in an empty mods folder and 1 folder until i got the crash again starting with x64(letter) folders... i put them all in... game loaded in ready to play... SWEET!
so then i put in common and x64 in ... still would load great... * so far ive got modifications in every one of these folders *
so then i threw in the update folder.... WHAMOH! crash.
okay dayme... i pulled out update.rpf ....... game loaded in ready to play...
so i found the issue there no surprise to me. i proceeded to try each folder in the file but i would get crashes every single time until i deleted everything out of the folder... but then id just get an infinite load screen with the pointer words (i) you see during the load screen.
the oddity is here. i pulled out my update.rpf folder... and went to the current one and copied it to mods folder... and i still crash.
so it seems like having the update.rpf inside of mods folder at all causes 1 issues... and causes CTD upon loading.
anyone have any ideas how to overcome this or fix it all together? lol other than playing a different game or modless gta? 
UPDATE 1 unsolved : so i realized i didnt have the new dlcpacks installed into x64 on my mods folder... so i added them in in hopes that would help but this did not help with the new update.rpf or my old one... still crashing with new update.rpf untouched inside of mods folder also tried my old+new dlclist file (with my modded vehicles) in both common and update locations in my mods folder... no success. ctd.
btw my prior to the latest update that broke reverting... i had a fully functional game i could play to my hearts content with 0 crashing ever. hours and hours. that was even this year... this version was a reverted version back to 1868.1 worked flawlessly until the evil update.
