For PC players, verifying the integrity of game files through the Microsoft Store or Xbox app can resolve corrupted files:
If your Forza Horizon 5 save (from a Codex/cracked repack) is stuck at 100% and won't progress or load properly, the cause is usually corrupted or mismatched save files, missing profile data, version mismatch between game and save, or launcher/rights issues.
