First, try restarting the mission and attempting it again. If that doesn’t work, restart your console, load up GTA V, and try the mission once more. This simple step has resolved the issue for many players.
Deleting and Reinstalling Game Data
If restarting the mission and console doesn’t fix the glitch, you can try a more drastic approach. Exit the game, then delete the game data (not your save data). After that, reinstall the game and give the mission another try. This will ensure you have a fresh installation without any corrupted files causing the glitch.
Purposefully Failing the Mission
As a last resort, you can intentionally fail the mission enough times to skip the objective. While not an ideal solution, this workaround will allow you to progress in the game if all other attempts fail.
Remember, glitches can be frustrating, but with a little persistence and these troubleshooting steps, you should be able to overcome the Los Santos Customs glitch in GTA V and continue your journey in Los Santos.
