If you have been trying to survive the apocalypse in Quarantine Zone: The Last Check only to be stopped by a sudden Fatal Error, you are not alone. Many players, particularly those using AMD graphics cards, have reported persistent crashes that prevent the game from launching. Fortunately, there are several ways to resolve the issue and get back into the quarantine.
The Official AMD Driver Fix
The primary cause of these crashes stems from conflicts between the game engine and recent AMD Adrenalin drivers. Developers have confirmed that versions later than 25.09.02 can trigger CTDs (Crash to Desktop). To address this, you will need to downgrade your AMD driver to version 25.09.02 or 25.09.01.
Simply installing the older driver over the new one is insufficient. Doing so risks leftover registry entries that can cause further instability.
Using Display Driver Uninstaller (DDU)
For a clean installation of the older AMD driver, use DDU:
- Download the driver: Visit AMD’s official site and get version 25.09.02 but do not install it yet.
- Get DDU: Download the latest Display Driver Uninstaller from WagnardSoft.
- Go offline: Disconnect from the internet to prevent Windows Update from installing newer drivers automatically.
- Safe Mode: Launch DDU and select “Reboot to Safe Mode.”
- Clean install: In Safe Mode, choose AMD and click “Clean and restart.”
- Install the driver: Once your PC restarts, install the older driver you downloaded.
This method ensures that all remnants of newer drivers are removed and the older driver integrates cleanly with your system.
Additional Troubleshooting Steps
If you are not on AMD or the issue persists, several other steps can improve stability:
- Launch Options: Open your Steam library, right-click the game, and select Properties. In the launch options, type -dx11 or -dx12 to force the game to use a specific DirectX version.
- Run as Administrator: Navigate to the game’s installation folder, right-click the executable, and choose “Run as Administrator” to avoid permission conflicts.
- Disable Overlays: Shut down Discord, GeForce Experience, and any other overlay applications. Tools like MSI Afterburner or Razer Synapse may also interfere with the game engine. Consider a clean boot if problems continue.
Why This Happens
The Fatal Error typically occurs during shader decompression, especially on certain CPUs and GPUs. For AMD users, recent driver updates introduced changes that clash with the game’s rendering pipeline. Updating or rolling back drivers addresses the issue for most players. Intel users may occasionally encounter similar crashes linked to unstable system configurations or third-party software conflicts.
Getting Back to the Game
Once these steps are complete, launch the game again. You should notice a significant reduction in crashes. For persistent issues, verifying the game files via Steam or reinstalling the game after cleaning drivers can help.
Staying informed via the developer’s forums and community threads is also recommended, as patches or official driver updates may offer permanent solutions.
