Fix: “An Unexpected Error Has Occurred Code” Rise of the Ronin

When launching Rise of the Ronin, if the game crashes and shows an application error, it typically points to a memory access violation—meaning the game attempted to access protected or invalid memory. This issue can be caused by outdated graphics drivers, corrupted game files, or conflicting software running in the background.

Now that we’ve covered the possible causes, let’s walk through the solutions step-by-step. Before you begin, make sure your system meets the minimum requirements for the game, and consider closing all unnecessary background applications to avoid memory conflicts or resource overload.

1. Perform a Clean Restart

A clean boot is a troubleshooting method that starts Windows with only the essential services and drivers. When you perform a clean boot, it helps isolate software conflicts by disabling third-party applications and background services. This can prevent unnecessary programs from interfering with the game and potentially triggering the 0xC0000005 error.

1. Press Windows Key + R to open the Run dialog, type msconfig, then click OK or press Enter.
2. In the System Configuration window, navigate to the Services tab and check the box labeled Hide all Microsoft services (this protects essential Windows services from being disabled).
3. With only third-party services visible, click Disable all at the bottom, then click Apply followed by OK to save your changes.
4. Switch to the Startup tab and click Open Task Manager to manage startup programs.
5. In Task Manager’s Startup tab, disable all enabled applications by right-clicking each entry and selecting Disable (this prevents unnecessary programs from launching at startup).
6. Close all windows and restart your computer to boot with only essential services and programs running. After restarting, check if your original issue is resolved.

2. Verify Game Files

Verifying the integrity of game files checks for missing or corrupted files and automatically replaces them with clean copies from the game’s servers. This process helps ensure that no damaged or altered files are causing crashes or triggering the 0xC0000005 error during launch.

1. Open the Steam client on your computer and click on the Library tab at the top.
2. Locate Rise of the Ronin in your game list, right-click it, and select Properties from the context menu.
3. In the Properties window:
   • Select the Installed Files tab from the left sidebar.
   • Click the Verify integrity of game files button.

   Note: This process may take several minutes depending on your game size and hardware.

4. After verification completes, close the Properties window. Fully exit Steam (right-click system tray icon > Exit), restart Steam, and launch Rise of the Ronin normally.

3. Adjust In-Game Graphics Settings

In some cases, this error can be triggered by high graphics settings that put excessive load on your system. Lowering these settings can help reduce the strain on your VRAM and system memory, which may prevent the game from crashing. If you’re experiencing this issue, try reducing the resolution, texture quality, and effects to see if stability improves.

1. Launch the game and navigate to the Settings menu.
2. Select the Visuals tab and apply these recommended settings:
   • Display Mode: Fullscreen
   • Resolution: Your monitor’s native resolution
   • VSync: Off
   • Graphics Quality: Medium (adjust higher if your PC can handle it)

   

3. Select Save Settings or Apply, then choose Exit Game to close completely.
4. Restart your game normally and check if the original issue is resolved.

4. Update Graphics Drivers

If your graphics drivers are outdated or not properly optimized for Rise of the Ronin, they can lead to crashes, performance issues, or visual glitches.

Note: For NVIDIA users, we recommend updating to NVIDIA driver version 572.83 or newer, with the latest version always being preferred. Driver 572.83 introduced support for Rise of the Ronin in the NVIDIA App, including personalized settings and configuration profiles specifically tailored for the game.

2. Locate the driver download section and:
   • Select your exact GPU model from the dropdown menus
   • Choose your operating system version
   • Download the latest Game Ready Driver (NVIDIA) or Adrenalin Edition (AMD)

   

3. Run the downloaded driver installer:
   • Select Custom Installation
   • Check Perform clean install (recommended)
   • Follow all on-screen prompts
4. After installation completes, restart your computer to finalize driver changes.
5. Launch your game to check if performance issues are resolved.

As a last resort, you can try reinstalling the game. This will completely remove all files and reinstall fresh ones, eliminating any corrupted files that may be causing the error.
