Gray Zone Warfare error codes and crash fixes
Every error, crash and connection failure we have a fix for, one page per code. Before the fix, each page says whether the problem is your machine or the studio's servers — because if it's theirs, no amount of verifying game files will help, and the only useful answer is whether it's happening right now.

Things you can fix
Crashes, install faults and driver conflicts. Find your symptom, work the steps in order, stop when it launches.
Gray Zone Warfare error 0x0001000F: failed to authenticate (fix)
At launch or on the server-select screen, the game shows "Network Error Occurred (0x0001000F) Failed to authenticate with the online services", or "NETWORK ERROR OCCURRED (0x00010004) – Steam Authorization Failed" with Reconnect and Quit buttons, and you can't get in.
Gray Zone Warfare network error 0x0003000F: stuck loading (fix)
The loading screen stalls early (12% in the first report), then "Network Error Occurred (0x0003000F)" appears and you're back at the menu. It repeats on every server, mode and region you try, often on your first launch.
Gray Zone Warfare 0x00020008: anti-cheat module failed to load
The game won't start and shows "The client failed to load the anti-cheat module at startup (0X00020008)".
Gray Zone Warfare 0x0002000A: failed anti-cheat runtime check
The game closes or won't connect with "The client failed an anti-cheat client runtime check (0x0002000A)".
Gray Zone Warfare "Game Security Violation Detected (#00000022)"
At launch the game shows "Game Security Violation Detected (#00000022)" and doesn't start.
Gray Zone Warfare "Invalid game executable path!" (fix)
Launching shows "Invalid game executable path!" followed by the path to `GZWClientSteam-Win64-Shipping.exe`, and the game doesn't start.
Gray Zone Warfare "Easy Anti-Cheat not installed": the fix
The game refuses to launch because Easy Anti-Cheat isn't installed, even though you installed the game through Steam.
Gray Zone Warfare stuck on loading screen with no error (fix)
The game sits on the loading screen indefinitely with no error message, and never reaches the main menu.
Gray Zone Warfare "GPU Crash dump Triggered": official fixes
The game closes and the UE-GZW Crash Reporter opens with "An Unreal process has crashed: UE-GZW" and "GPU Crash dump Triggered" in the crash details, often mid-raid or while deploying.
Gray Zone Warfare EXCEPTION_ACCESS_VIOLATION crash: what to try
The UE-GZW Crash Reporter opens with "Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x…", often at 100% loading or right as you join a server.
Gray Zone Warfare "Out of video memory" crash: the fix
The game crashes with an "Out of video memory" or "low video memory" message, sometimes before reaching the title screen, even on a graphics card with plenty of VRAM.
Gray Zone Warfare Skalla.dll error on launch: cause and fix
The game won't start and shows an error about loading or missing `Skalla.dll`.
Gray Zone Warfare "This application requires Steam" (fix)
Launching shows "This application requires Steam", even with Steam open and signed in.
Gray Zone Warfare "Easy Anti-Cheat Action (0x0002000F)"
Joining a server fails partway through loading (around 72% in the first report) with "EASY ANTI-CHEAT ACTION (0X0002000F)".
Gray Zone Warfare "Easy Anti-Cheat Action (0x00020011)"
The game shows "EASY ANTI-CHEAT ACTION (0X00020011)" and won't let you play.
Gray Zone Warfare "VOIP Connection Lost": voice chat not working
A "VOIP Connection Lost" popup appears and voice chat stops working, even with the right microphone selected in the game's settings.
Gray Zone Warfare "PresentInternal failed" D3D12 crash
The game crashes every 5–10 minutes, sometimes opening the Unreal crash reporter, with "PresentInternal(SyncInterval) failed with error 80004004" in the log, and lines mentioning "slDLSSGGetState" and "Invalid backbuffer resource extent (0 x 0)".
Things you cannot
Queues, capacity limits and login failures. These are server-side — every page below links back to live status rather than a fix you can perform yourself.
Gray Zone Warfare network error 0x00030004: disconnected on load
After "Synchronising live data" and the loading bar, the game shows "Network Error Occurred (0x00030004)" and drops you back before you load into the server, in PvE and PvEvP and across regions.
Gray Zone Warfare "Online Persistence Error (0x00040008)"
Mid-raid you're kicked to the main menu with "Online Persistence Error (0x00040008) – Failed to save player's progression. Please join a different server or try again later." Gear, loot or task progress may be gone when you return, and during server trouble it can repeat every 15–20 minutes.
How these are graded
Every fix step carries a label. Confirmed means players demonstrably got back in with it, or the studio said so directly.Reported means it worked for some people and not others. Unconfirmed means it's circulating and there's no evidence either way yet. The distinction is the point — a page that lists five fixes with equal confidence costs you an evening.
