Sadly, the game doesn't offer a way to undo the ending of the GTAV story. The developers designed it to be a linear progression towards the conclusion, and while there are different endings to experience, there's no option to reverse the outcome once it's been achieved. This is a common design choice in many story - driven games to maintain the integrity of the narrative.
Sadly, there's no option to undo the ending of GTA V story. Rockstar Games has created a linear narrative structure for the story mode. When you reach the end, it's the end of that particular story arc. You can always start a new playthrough and make different choices this time around, but you can't go back and change the ending of a completed playthrough. Even mods, which can sometimes change aspects of the game, typically don't allow for the undoing of a story ending as it would disrupt the core design of the game's narrative.
It depends on the platform. Some platforms may have a recycle bin or a short - term recovery option for recently deleted stories. For example, on Instagram, if you delete a story very recently, there might be a chance to recover it within a certain time frame. But generally, once a story is permanently deleted from the system, it's very difficult, if not impossible, to undo the deletion.
It depends. Sometimes, if you have a backup or the platform has a recovery feature, you might be able to undo it. But often, once it's deleted, it's gone for good.
