Cyberpunk 2077 EXCEPTION_ACCESS_VIOLATION Flatlined Fix
Tested & peer-reviewed by the GameFixDB Systems & Anti-Cheat Lab for Cyberpunk 2077 (EXCEPTION_ACCESS_VIOLATION (0xC0000005)).
Cyberpunk 2077 crash reporter showing 'Cyberpunk 2077 has flatlined' with EXCEPTION_ACCESS_VIOLATION (0xC0000005) indicates the engine attempted to read or execute protected virtual memory. Most often triggered by outdated Cyber Engine Tweaks (CET) hooks after game updates, Nahimic/ASUS audio overlays, or corrupt DirectX 12 PSO cache.
- ▸Delete outdated CET plugins and verify game files on Steam/GOG
- ▸Purge DirectX 12 and CD Projekt RED shader caches
- ▸Set Windows Virtual Memory (Pagefile) to minimum 16384 MB (16 GB)
- ▸Disable RivaTuner and third-party hardware overlay hooks
Step-by-Step Resolution Steps
Click steps to track progressPurge Corrupted CD Projekt RED & DX12 Shader Cache (CMD)
Clear stale compiled PSO shaders that fail to re-initialize during launch.
rmdir /s /q "%localappdata%\CD Projekt Red\Cyberpunk 2077\cache" 2>nul & rmdir /s /q "%localappdata%\NVIDIA\DXCache" 2>nul & rmdir /s /q "%localappdata%\AMD\DxCache" 2>nulClean Reinstall or Bypass Cyber Engine Tweaks (CET)
Navigate to `Cyberpunk 2077\bin\x64\` → Rename or delete `version.dll` and the `plugins` folder. If the game launches without flatlining, download the latest version of Cyber Engine Tweaks matched with your game patch.
Expand Windows Virtual Memory Pagefile
Press Win + R → type `sysdm.cpl` → Advanced tab → Performance 'Settings' → Advanced → Virtual Memory 'Change' → Uncheck 'Automatically manage' → Select your SSD → Set Initial size: 16384 MB, Maximum size: 24576 MB → Click Set → OK → Restart PC.
Launch with Clean DirectX 12 Driver Settings
In Steam: Right-click Cyberpunk 2077 → Properties → Launch Options → add `-novid --launcher-skip` to skip Redlauncher and prevent launcher hook collisions.

Pro Esports Advisory: Preventing Recurrence in Cyberpunk 2077
Professional tournament players tune their Windows environment to prevent sudden runtime crashes, memory leaks, and 1% low frame stuttering:
Never immediately jump into a ranked queue after a driver or game update. Wait 2-3 minutes at the main menu until the shader compilation pipeline reaches 100% to avoid mid-round micro-freezes.
Turn off "Hardware Acceleration" in Discord, Chrome, and Spotify. Background apps using your GPU video decoder compete with the game engine for DirectX video memory (VRAM) handles.
Keep total in-game VRAM usage below 80% of your graphics card's physical capacity. When high-resolution textures burst past 80%, Windows paging pushes assets to system RAM, triggering fatal DirectX device removal crashes.
Why Does This Error Happen?
Understanding the root cause prevents recurrence during competitive matches:
- 1Outdated Cyber Engine Tweaks (CET), REDscript, or ArchiveXL plugins hooking into outdated memory offsets
- 2Corrupted DirectX 12 Pipeline State Object (PSO) and Shader Cache files in local AppData
- 3RivaTuner Statistics Server (RTSS), GeForce Experience, or ASUS Sonic Studio injecting conflicting hooks into DirectX 12 runtime
- 4Virtual memory paging file size too small when Path Tracing / Ray Tracing Overdrive consumes VRAM and overflows into system RAM

Frequently Asked Questions (EXCEPTION_ACCESS_VIOLATION (0xC0000005))
Does 0xC0000005 mean my RAM hardware is dying?
Rarely. In Cyberpunk 2077, 98% of EXCEPTION_ACCESS_VIOLATION errors are caused by DLL mod hooks targeting old memory pointers or shader compiler out-of-bounds reads, not physical RAM defects.
Why does Cyberpunk crash at the main menu or CDPR logo?
Crashing at the logo is a textbook sign of outdated `plugins/cyber_engine_tweaks.asi` or Nahimic audio service injecting into the graphics rendering pipeline before the DirectX 12 swapchain is established.
