How to fix ERR_MEM_MULTIALLOC_FREE error in GTA V?

Issue: CI am getting a rather strange error whenever I try to launch story mode in GTA V on Windows, it says “ERR_MEM_MULTIALLOC_FREE.” It stops me from playing the game, and I want to continue with the story. Any idea on how to fix this? I tried reinstalling the game, but the problem persists.

Solved Answer

Grand Theft Auto V is the seventh iteration of the franchise, released in 2013 by Rockstar Games. Even with its successful predecessors like San Andreas, this series entry is deemed one of the most successful ones the publisher had ever released, with more than 165 million copies sold as of spring 2022.[1] The game continues to be plaid by millions of people even after all these years, with an online multiplayer mode being especially active.

Unfortunately, not all players can experience the game as intended, as they reported encountering the ERR_MEM_MULTIALLOC_FREE error, which they can receive it under varying circumstances. The full message of the error reads as follows:

Game memory error. Please reboot and restart the game.

The message claims that restarting or rebooting the game should be the next step, and most people follow this advice. It usually doesn't work, however, and users are stuck with the error and are not able to play GTA 5.

As it is with many issues that plague systems, there is no one resulting for everyone, although the most common reason for the ERR_MEM_MULTIALLOC_FREE error is the game file corruption. This can usually be fixed by reinstalling the game or verifying game files. Mods[2] are another reason why games might experience difficulties, as they are introduced by third parties and frequently get corrupted when a new game version is released.

You can also access your GPU manufacturer's website and download the latest driver from there.

Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speeds. The best solution for your ultimate privacy is Private Internet Access – be anonymous and secure online.
