How to Fix 'Serialization Error Action Needed' in Ready or Not
The "Serialization Error Action Needed" in Ready or Not often comes with the message "Corrupt data found, please verify your installation." This error is related to Unreal Engine, and there are several steps you can take to address it.
1. Verify Your Installation

- Go to your Steam Library and find Ready or Not.
- Right-click on it and select Properties.
- Click on Installed Files.
- Click on Verify Integrity of Game Files.
This process will check for any missing or damaged files and re-download them if necessary. After verifying, try running Ready or Not again. If the issue persists, you may need to try additional solutions.
2. Remove Any Mods

3. Reinstall Your Mods
If you want to use mods, reinstall them one at a time. Visit Nexus Mods, Mod.io, or your preferred mod source and check the update date of each mod.
- Only install mods that have been updated since July 2024, when Ready or Not switched to Unreal Engine 5.
- Install a mod, then launch the game to test it.
- If the error reappears, the last mod you installed is likely the culprit. Remove it and try another.
If none of these steps work, consider uninstalling and reinstalling Ready or Not from scratch. While it's rare, a corrupted hard disk could also be the issue, but most reports indicate outdated mods as the primary cause.
By following these steps, you should be able to fix the "Serialization Error Action Needed" in Ready or Not and continue enjoying this intense tactical shooter.
Ready or Not is available now for PC.
