How to Fix Duet Night Abyss Fatal Error on PC?
In most cases, this fatal error comes from software conflicts, missing files, or outdated system components. It may look random at first, but the cause is usually clear once you check the basics. The fixes below focus on stability, system access, and game file health. Follow them in order and test the game after each one.
Fix #1: Update Graphics Drivers
This error often appears when your graphics driver is outdated or unstable. Duet Night Abyss relies on the GPU driver to handle visuals and memory correctly. When the driver fails, the game crashes. Updating the driver helps restore proper communication between the game and your graphics card.
Follow the steps below to easily update your graphics drivers.
- Right-click the Start menu
- Open Device Manager
- Expand Display adapters
- Right-click your NVIDIA or AMD GPU
- Select Update driver
- Choose Search automatically for drivers
- Restart your PC
Launch the game again after the restart.
Fix #2: Verify Duet Night Abyss Game Files
Game files can become corrupted due to interrupted downloads or system errors. When this happens, the game may crash during startup or loading. Verifying files checks the game folder and replaces damaged data.
Here are the following steps which help you to verify game files.
- Open the game launcher
- Go to your game library
- Select Duet Night Abyss
- Open game settings
- Click Verify or Repair files
- Wait for the scan to finish
- Restart the launcher
This often fixes crashes that happen without warning.
Fix #3: Install or Repair Visual C++ Redistributables
Duet Night Abyss depends on Visual C++ Redistributable packages to run properly. If these system files are missing or damaged, the game may crash instantly at launch. Installing the correct versions restores required Windows components.
Download the official Visual C++ Redistributable installers from Microsoft, install both x64 and x86 versions if available, and restart your PC before testing the game again.
Fix #4: Disable Overlays and Background Apps
Overlays and background apps use system memory and can conflict with Unreal Engine processes. When several run together, crashes become more likely.
Try these simple steps to quickly disable overlays.
- Open Discord settings
- Turn off the in-game overlay
- Open GeForce Experience
- Disable the in-game overlay
- Close screen recording tools
- Exit unused background programs
Restart the game after closing these apps.
Fix #5: Run the Game as Administrator
Sometimes Windows blocks the game from accessing important system files. This can trigger crashes during launch or loading. Running the game as administrator gives it full permission.
The following steps will show you how to run the game properly.
- Right-click the game shortcut
- Click Properties
- Open the Compatibility tab
- Check Run this program as administrator
- Click Apply
- Click OK
Launch the game and check stability.
Fix #6: Update Windows and DirectX
Outdated Windows files or DirectX components can cause compatibility issues. Keeping the system updated helps prevent crashes.
Follow these easy instructions to update Windows and DirectX.
- Open Windows Settings
- Go to Windows Update
- Click Check for updates
- Install all available updates
- Restart your PC
- Launch the game again
Fix #7: Check System Memory and Virtual Memory
Low system memory can cause fatal errors during gameplay. If your RAM or virtual memory is too low, the game may crash. Check your RAM usage in Task Manager. Increase virtual memory if needed. Close memory-heavy apps before playing to free resources.
Fix #8: Reinstall Duet Night Abyss (Last Option)
If the fatal error continues after trying all fixes, a clean reinstall may be necessary. This helps remove hidden file corruption, broken settings, or failed updates that other fixes cannot repair. Reinstalling gives the game a fresh start on your system.
Uninstall the game completely, restart your PC, then download and install it again from the official source. After installation, launch the game before adding mods or extra software.
