I think what is causing the issue are these 2 files:
socialclub.dll (size before update: 5084ko, new size: 5106ko) and SocialClubHelper.exe (previous size : 2555ko, new size : 2561ko)

@littlefilms So first i made a backup of all the files located here :
C:\Program Files\Rockstar Games
C:\SAVE\YOUR COMPUTER NAME\Documents\Rockstar Games

• Then i have installed the Rockstar Game launcher.
• Then i have launched the vanilla game not modded.
• Then i have disabled my internet connection.
• Then i have downgraded the game to its previous version (reinstall of all .exeS and update.rpf)
• Then i have gone in the above mentionned folders and replaced everything with the backup files.

It works but i can only play with Internet Connection disabled. I do not know yet if @iammistahwolf method works or not :

@iammistahwolf said in Beware August 11th!:
you could go 5 days w/out being online, then turn your system clock back to the last day of that grace period (while offline) and you could play indefinitely.

.
But in any case as @Rstein method (thanks a million to you!) works on my side, i'm not even sure i will update this game ever again.

@R3QQ It worked for me but only after i delete all the files in My Documents/Rockstar Games and Programs/Rockstar Games and replaced them with the backup files i had copied before updating.

I figured out that Rockstar has updated some files linked to the social club. there are slight differences in size between the 1868 and the 2060 social club files.

Enjoy

@Algonquin1234 Yes sure, asuming you are willing to update your game this is correct.

But the issue is different this time because apparently it is not even possible to downgrade your game to the previous version as neither GTAVlauncherBypass.asi nor No_GTAVLauncher.exe works.

Meaning that from now on i will be forced to update the game everytime R* updates GtaO (although i do not play online at all).

@Rstein Thank you for the protip. Unfortunately i play on the DVD retail version.
Are you aware of any similar method existing for non steam users ?

Neither the gta v Launcher bypass.asi nor the No_GTAVLauncher.exe are working on my side (i posted my issue in this thread if anybody is willing to help).

@carsfan200 You're welcome

Hello,
If you are an experienced modder and have a solution, or if you are simply encountering the same issue (confirming i'm not the only one) i would be happy to read your comment !

I have the DVD version of the Game, not the Steam.
Since yesterday's GTA O update, i cannot play with mods anymore (i know we need to wait for ScripthookV update but the below workaround that are normally working, are not helpful this time).

What i did:

• I have installed the Rockstar Games Launcher.
• I have logged into my Social Club account
• I have let RGL installing the "11 august 2020" GTA Online MAJ

Once done i have tryed to downgrade GTAV to its previous version by putting back the previous version of :

• GTA5.exe
• GTAVLanguageSelect
• GTAVLauncher
• PlayGTAV
• update.rpf
• and renaming my mods folder to something else
  .

WORKAROUND ATTEMPT 1 : No_GTAVLauncher
i have put in the GTAV root folder the files from :
https://www.gta5-mods.com/tools/no-gtavlauncher
I tryed all three versions available : the 0.9 the 1.0 and the 2.0
--> Tryed to launch the game (by clicking on No_GTAVLauncher.exe) ------> Error Message. The Game won't launch

.
.
WORKAROUND ATTEMPT 2 : GTAVLauncherBypass
I think this mod is not available anymore on this website, but i have an old backup of it on my hard drive.
i have put in the GTAV root folder these files :

• GTAVLauncherBypass.asi
• GTAVLauncherBypass.ini
  (settings in this ini : bypass_launcher_check = true //// bypass_intro_video = true //// bypass_legal_message = true)
  --> Tryed to launch the game (by clicking on GTA5.exe) ------> Error Message. The Game won't launch
  --> Tryed to launch the game (by clicking on No_GTAVLauncher.exe) --> Error Message. The Game won't launch

.
.
WORKAROUND ATTEMPT 3 : Rage Plugin Hook
I have installed the latest available version
https://ragepluginhook.net/Downloads.aspx?Category=1
--> Tryed to launch the game (by clicking on the Rage Plugin exe)
------> I end up on the Rockstar Game Launcher screen again
and the RGL tryes to update my game to the latest version (...as i have downgraded it 5 min ago) so it's impossible to play with Mods.

My 2 questions are:
- Am i the only one facing this issue ?
- Anybody has a working solution to share ?

Thanks in advance !

(Edit 1) : forgot to mention that i have not modified deleted or reinstalled any file located in the My documents/Rockstar Games folder containing game backups, social club infos, rockstar editor clips etc...

If you have made a recent back up of your game before the crashes, then simply reinstall the latest working version, and retry to install your recent mods one by one to see which one is causing the crashes.

If you have not made a recent backup before the crashes, unistall the 10 last mods you have installed and try to launch the game. If it still crash, then you will need to reinstall a clean game.

In the future always back up your game after every change, and keep at least two different backups (backup n-1, and backup n-2), so you do not lose everything next time your game will crash, because trust me, it will happen again.

If you have installed multiple add on dlc in your game, check that your issue is not similar as this one :
