If you're using the steam version of GTA right click on your game and click "properties" after that go to update and under "automatic updates" select "update when i launch the game" If you're using the Epic launcher, click on your account and go to the settings tab, then go down to Manage Games and look for the tab labeled "GRAND THEFT AUTO V" click on it and there should be a box labeled "Auto-Update GRAND THEFT AUTO V" uncheck that. Also make sure that before you launch GTA you save the game files that have the GTA logo on them, I attached an example below. Hope this helps!
