Forza Horizon 5 error code FH5-100 indicates a cloud save conflict — the game has detected a mismatch between your local save data and what is stored in the cloud. This typically happens when the game is played on multiple devices, after an internet outage during a save, or following a game update that interrupted sync. The good news is that this is a software issue and can almost always be resolved without losing your progress.

How to Fix Error Code FH5-100

  1. Check Xbox Live / Microsoft Server Status

  2. Restart the Game and Your Device Completely

  3. Sign Out and Sign Back In to Your Microsoft Account

  4. Choose Which Save to Keep When Prompted

    Warning: Choosing the wrong save will overwrite the other. Take note of the timestamps shown for each option before selecting. This action cannot be undone.

  5. Clear the Xbox App or Console Cache

    Do not delete your saved game files or the entire game package folder — only the LocalCache contents.

  6. Check and Reset Your Internet Connection

  7. Repair or Reinstall the Game (PC Only)

    Using 'Reset' will clear locally stored game data on your PC. Ensure your save has successfully synced to the cloud before proceeding. Do not use Reset if you have unsaved local progress you want to keep.

  8. Disable VPN or Proxy Services

When to Call a Professional

If none of the above steps resolve error FH5-100 and you suspect your save data is permanently corrupted or lost, contact Microsoft Xbox Support directly at support.xbox.com. Provide them with your Gamertag and a description of the error. Xbox Support can investigate your cloud save history and may be able to restore a previous backup of your game data. This is the appropriate escalation path since there is no physical hardware to service — the issue resides on Microsoft's servers or your account.

Frequently Asked Questions

Will Forza Horizon 5 error FH5-100 delete my save data?
Not automatically. Error FH5-100 is a sync conflict — it means the game cannot determine which save is correct. Your data is not deleted unless you manually choose to overwrite one save with another. When prompted, carefully compare the timestamps of your local and cloud saves before making a selection.
Why does FH5-100 keep coming back every time I launch the game?
If the error reappears repeatedly, it usually means the sync conflict was not fully resolved — the game keeps detecting a mismatch. Make sure to always close the game properly (use Quit, not just switching away), maintain a stable internet connection while playing, and avoid playing on two different devices within a very short time window without letting the cloud sync complete each time.
Does FH5-100 only happen on PC or does it affect Xbox consoles too?
Error FH5-100 can occur on both Xbox consoles (Xbox One and Xbox Series X|S) and Windows PC via the Xbox app. It is tied to the Microsoft cloud save system, which is used across all platforms. The fix steps differ slightly between platforms but the underlying cause is the same.
Can I play Forza Horizon 5 offline to avoid this error?
Yes. You can set your Xbox or PC as your 'Home' console/device and enable offline mode. On Xbox, go to Settings > General > Personalization > My home Xbox and enable it. On PC, open the Xbox app, go to Settings, and turn on Offline permissions. When playing offline, the game uses your local save. Just be aware that when you reconnect, another sync prompt may appear — always keep your internet connected when launching and closing the game to keep saves in sync.
How long does it take for cloud saves to sync in Forza Horizon 5?
Cloud saves in Forza Horizon 5 typically sync within a few seconds to a minute when you exit the game on a stable connection. However, on slower connections or after very long play sessions with lots of progress, it can take up to 2-3 minutes. Always wait for the game to fully close and return to the home screen before turning off your device or switching to another platform to avoid triggering error FH5-100.
