Fortnite Keeps Crashing After an Update? Here's the Fix

Most Fortnite crashes right after a Windows or game update come from one of three things: a stale GPU driver that no longer matches the new build, a corrupted GameUserSettings.ini, or damaged game files. The fastest fix that clears the majority of cases: delete %localappdata%\FortniteGame\Saved\Config\WindowsClient\GameUserSettings.ini, install the latest Game Ready / Adrenalin GPU driver, then Verify files in the Epic Games Launcher. Steps below, in order.

Fortnite crashing after an update — the cache fixes

Clear shader/config cache
Delete %LOCALAPPDATA%\FortniteGame (config, cache, shader cache) — stale post-update shaders cause crashes
Rendering mode
Switch Settings -> Video -> Rendering Mode to DirectX 11 or Performance Mode (DX12 is less stable on many GPUs)
Verify
Epic Launcher -> Fortnite -> settings -> Verify
Repair EAC
...\FortniteGame\Binaries\Win64\EasyAntiCheat\EasyAntiCheat_Setup.exe -> Repair

Error codes

GPU crashed or D3D device removed DirectX lost the graphics device mid-launch

Cause: After a Windows update the old GPU driver stops matching the DirectX runtime, so Fortnite loses the render device on startup. Overclocks and aggressive RGB/overlay software make it worse.

Fix:
  1. Do a clean GPU driver install (DDU in safe mode, then latest NVIDIA Game Ready / AMD Adrenalin driver).
  2. Turn off any factory or manual GPU overclock; test at stock clocks.
  3. Disable overlays (Discord, GeForce Experience, MSI Afterburner/RivaTuner, RGB software).
  4. In Windows: Settings > Display > Graphics > disable Hardware-Accelerated GPU Scheduling (HAGS), reboot.
LS-0013 Launch prerequisites failed to install

Cause: The Epic launcher could not install a required runtime (VC++ / DirectX) after the update, so the game will not start.

Fix:
  1. In the Epic Launcher: Library > Fortnite > ... > Manage > Verify.
  2. Install the latest Microsoft Visual C++ Redistributable (x64) and the DirectX End-User Runtime.
  3. Run the Epic Games Launcher as administrator, then launch Fortnite.

Fixes that work for most Fortnite errors

  1. Delete the config file: close Fortnite, open %localappdata%\FortniteGame\Saved\Config\WindowsClient, delete GameUserSettings.ini, relaunch (Fortnite rebuilds it with safe defaults).
  2. Update your GPU driver: after any Windows update the vendor usually ships a fixed Game Ready / Adrenalin driver within 1–2 weeks — install it clean.
  3. Verify game files in the Epic Launcher (Manage > Verify) to repair anything the update corrupted.
  4. Run Fortnite as administrator (right-click the shortcut > Run as administrator) so it can bypass UAC.
  5. Disable Hardware-Accelerated GPU Scheduling (Settings > Display > Graphics > Change default graphics settings) and reboot.
  6. Close background apps and overlays (Discord, browsers, RGB and monitoring tools) that hook into the game.
  7. If it started right after a specific Windows update, roll it back or use System Restore to a point before the update.

FAQ

Why does Fortnite keep crashing after a Windows update?

The Windows update usually changes the graphics/DirectX runtime while your GPU driver stays on the old version, so Fortnite crashes on launch. Installing the latest Game Ready / Adrenalin driver (clean install) fixes most of these cases.

How do I fix Fortnite not launching at all after an update?

Delete GameUserSettings.ini in %localappdata%\FortniteGame\Saved\Config\WindowsClient, then Verify files in the Epic Launcher and run it as administrator. If a prerequisite failed (LS-0013), reinstall the latest Visual C++ Redistributable.

Will deleting GameUserSettings.ini lose my progress?

No. That file only stores video/keybind settings, not your account, skins or progress — Fortnite recreates it with defaults on the next launch.

Fortnite still crashes after updating drivers — what next?

Disable Hardware-Accelerated GPU Scheduling, remove any GPU overclock, and turn off overlays/RGB software. If it only broke after one specific Windows update, use System Restore to roll that update back.
