@TheMurderousCricket Also can you give more details about the crash issues you talked about, when using "No GTAVLauncher 2.0" ? Was it like normal crashing while playing or using specific mods?

@TheMurderousCricket To answer the question of profile corruption [Backing it up]. I stated that for 2 things:

1. Incase computer gets infected, Profile folder will be altered messing up the account token
2. If you reinstalled the game from archived copy on a different PC and you don't have internet connection.

Also yesterday i took the the big risk, i knew i would get screwed and would have to start all over again but it actually worked.
Made an archive of GTA V Retail Copy [84GB], copied my profile folder. Next i uninstalled GTA V + Social Club.

Extracted and placed files from the archive, installed social club., Blocked both exe files in firewall [no updates possible, set date to 13th Dec, installed mods. Booted game, account auto-signed in offline mode, verification skipped, game loaded with success.]

This topic is aimed at helping the users with Retail Copy of the game to continue playing in offline mode even after it asks for internet connection to verify the game activation after the token expires.

Requirements:

1. Legal retail copy of GTA V
2. ASI Loader
3. No GTAVLauncher 2.0
4. Social Club account

Install ASI Loader [Using OpenIV's ASI Manager]
Download No GTAVLauncher 2.0 from: https://www.gta5-mods.com/tools/no-gtavlauncher after download extract the files and only copy the "No_GTAVLauncher.asi" file to GTA V Directory.

Next boot up the game using GTA5.exe file. Let the game load in Story Mode through internet connection, this will create a fresh account token. After game is loaded in Story Mode, exit the game.

Navigate to taskbar [located at bottom side of the screen] click on windows logo button > Searchbar, search for "firewall" then click on "Windows Defender Firewall"

Advanced Settings > Outbound Rules, then right click on Outbound Rules > New Rule > Program, Click Next then key in the location of the executable > Block the connection, click Next & again click next and finally input the Program's Name and click finish.

Blocking the following exe files:

1. GTA5.exe
2. SocialClubHelper.exe

After you have finished blocking the exe files, Run the game again using GTA5.exe, It should load fine in offline mode and will continue to do so till 5 days. After that it will ask for verification, so exit the game, and set the system date to 4 days back and relaunch the game, This should bypass the verification and allow the game to load in offline mode without any issue, After game finishes loading you can safely set system date back to current one.

NOTES:

1. This has been only tested on Retail Copy of the game. So i don't know if it works on Steam copy.

2. Changing SYSTEM Date is required to be done everytime to make the game load in offline mode. i have been loading the game for about 12 days straight without any issues. For me it worked fine for 5 days after which it started asking for verification.

3. The SYSTEM date that you will always use to skip verification is the one that you used to first login into the game using online account in story mode, So make sure to write it down somewhere [ex: mine is 13th Dec 2018, so i always load the game using that date]

4. Make sure to copy the Profile folder and place it somewhere safe, incase it gets corrupted / deleted. located in [Documents > "Rockstar Games"]
