The GFSDK_ShadowLib.win64.dll runtime error in Grand Theft Auto V (GTA 5) is a frustrating issue that causes crashes, freezes, or prevents the game from launching, particularly on Windows 11 in 2025. Fortunately, this error is fixable with systematic troubleshooting. This guide walks you through every reliable solution, from basic checks to advanced fixes, ensuring you get back to Los Santos quickly.
Update NVIDIA Graphics Drivers
Outdated or corrupted NVIDIA drivers are the most common cause of this error, especially after Windows 11 updates in 2025
Open GeForce Experience (download from NVIDIA's website if not installed) or visit www.nvidia.com/drivers
Select your GPU model (e.g., GTX 1660, RTX 3060) and Windows version (11, 64-bit)
Download the latest driver and choose "Custom Installation" > check "Perform a clean installation" to remove old driver remnants
Install, restart your PC, and test GTA 5
If the error started after a recent driver update, try rolling back:
In Device Manager, right-click your NVIDIA GPU > Properties > Driver tab > Roll Back Driver (if available). Restart and test
Verify GTA 5 Game Files
A missing or corrupted GFSDK_ShadowLib.win64.dll file often stems from incomplete game installations or crashes.
Steam: Right-click GTA 5 in your Library > Properties > Installed Files > Verify integrity of game files. Wait for the process (5–15 minutes) and relaunch.
Epic Games: Go to Library > GTA 5 > three dots > Manage > Verify files
Rockstar Launcher: Open Settings > My Installed Games > GTA 5 > Verify Integrity
This replaces missing or damaged files, including the DLL, without reinstalling the entire game. Test GTA 5 afterward

Reinstall Microsoft Visual C++ Redistributables
GTA 5 relies on Microsoft Visual C++ libraries to run DLL files. Corrupted or outdated packages can cause this error
Open Control Panel > Programs and Features
Uninstall all Microsoft Visual C++ Redistributables (2015–2022, x64 versions). Don't worry—uninstalling is safe
Download the latest versions from Microsoft's website (search for "Visual C++ Redistributable 2015–2022 x64")
Install each package and restart your PC
Most GTA 5 installations need the 2015–2019 versions, but installing the latest (2022) covers all bases. Test the game after restarting
Update Windows 11
Windows 11 updates, like the 24H2 release in 2025, can introduce compatibility issues with game libraries
Go to Settings (Win + I) > Windows Update > Check for updates
Install all updates, especially optional ones related to .NET Framework or drivers
Disable Conflicting Software
Third-party software can interfere with GTA 5's DLL files, especially on Windows 11
Antivirus: Temporarily disable real-time protection in Windows Defender or third-party antivirus (e.g., Norton, McAfee). Add GTA 5's folder to the exception list
Overlays and Tools: Close Discord, Steam Overlay, MSI Afterburner, or NVIDIA ShadowPlay. Disable them in their respective settings
Clean Boot: Press Win + R > type msconfig > Services > Hide all Microsoft services > Disable all > Apply. Restart and test GTA 5
Prevention Tips
To avoid this error in the future:
Update NVIDIA drivers monthly via GeForce Experience
Verify game files after every major GTA 5 or Windows update
Avoid unverified mods or DLL downloads
