Re-install the exact same version of the Option File you were using when you created the save.

The primary cause of this error lies in a fundamental incompatibility between saved data—such as Edit Files, Option Files, or Master League saves—and the current version of the game’s database. PES 2021 relies heavily on live updates, which adjust player statistics, team rosters, and even kit assignments weekly. When a player saves their progress or installs a custom Option File (e.g., for real team names and kits), that data is tethered to a specific "Data Pack" or "Live Update" version. If the game subsequently downloads a newer update, the previously saved data becomes structurally obsolete. The game’s integrity check reads the old metadata and, unable to reconcile the differences, blocks the load. This is not a random bug but a deliberate, albeit blunt, failsafe to prevent crashes or corrupted simulations that would arise from, for instance, a 2021 roster trying to reference a player who has since been removed from the database.
