Why Does "UE4-HK Project" Crash Occur in Stray?

Before we fix the problem, let‘s quickly understand what causes the "UE4-HK_project Game has crashed and will close" error message.

UE4 refers to Unreal Engine 4, the powerful game development platform that builds Stray‘s gorgeous environments. The "HK" portion stands for Hong Kong – an internal project code name for Stray during production with BlueTwelve Studio.

So when UE4-HK crashes, it indicates a fault in rendering the game properly through Unreal Engine 4.

Most often, UE4 errors stem from:

Corrupted/Outdated Game Files

  • Missing textures, sound effects, unstable mods cause game code to break

Graphics Driver Compatibility

  • New games depend on updated driver software to run optimizations

System Configuration Issues

  • Conflicts with background apps (anti-virus, RGB tools), Windows version mismatches crash games

By targeting these problem areas specifically for Stray, we can narrow down and fix the cause of most "UE4-HK" crashes.

Method 1: Verify Integrity of Game Files

When game files become damaged or altered, errors ensue. Verifying integrity checks all game data against original master files and repairs anything that‘s gone awry.

Here is how to verify Stray through Steam, step-by-step:

  1. Launch Steam and select Library
  2. Right-click on Stray in your game list
  3. Choose Properties from the menu
  4. Select the Local Files tab
  5. Click Verify Integrity of Game Files
  6. Let scanning process fully complete

Stray Verify Game Files

This scans through Stray‘s thousands of individual files, locating and restoring anything broken or misshapen like a feline plastic surgeon.

For user Ragesmasen verifying uncovered two corrupted files causing crashes:

"I kept getting the UE4 crash on game start up. Verifying the game files found two corrupt files out of the 13k and downloaded fresh copies. Works fine now."^1

So there‘s an excellent chance verification fixes "UE4-HK" crashes by replacing bad code or graphics making Stray trip up.

Method 2: Install DXVK on Windows 7

One discovery made by user miltonius is that missing Vulkan drivers in Windows 7 crash Stray, but copying over a helper tool called DXVK resolves it:

"Copying the DXVK dlls into the game‘s bin folders got rid of the UE4 crash for me on Win 7."^2

Specifically DXVK converts DirectX commands into Vulkan code for better stability and speed.

Here‘s how to implement DXVK just for Stray in Windows 7 rather than globally:

  1. Download DXVK 1.10.2
  2. Extract x64 folder from downloaded archive
  3. Copy all .dll files in x64 folder
  4. Paste .dll files into SteamLibrary\steamapps\common\Stray\HK_Project\Binaries\Win64
  5. Launch the game again

Now Stray has DXVK automatically translating needed graphics commands behind the scenes!

Note: DXVK currently only works on Windows 7, not newer versions which have native Vulkan libraries built-in.

Method 3: Update Graphics Drivers

Modern games depend on up-to-date driver software to enable cutting-edge graphical features and stability tweaks. Outdated drivers severely hinder performance – triggering crashes like our "UE4-HK" culprit.

Keeping drivers fresh is essential especially for new releases like Stray.

Depending on your graphics card – either Nvidia GeForce or AMD Radeon – follow these guides to install latest game-ready drivers:

Update NVIDIA Drivers

  1. Download and install GeForce Experience
  2. In GeForce Experience app click on Drivers tab
  3. Select Check for Updates
  4. Download and install latest Game Ready Driver

GeForce Experience Drivers

Info: GeForce Experience always provides optimized drivers for your Nvidia GPU

Update AMD Drivers

  1. Go to AMD Drivers Site
  2. Click on Auto Detect to identify your AMD graphics hardware
  3. Select and download latest Adrenalin drivers for your card

Tip: Always pick Recommended driver option unless resolving specific issue

Fresh AMD or Nvidia drivers tailor Stray‘s graphical settings for maximum compatibility and stability. If you crashed before, relaunch after updating for smoothest sailing!

Bonus Solutions That Resolve Stubborn Crashes

For anyone still experiencing "UE4-HK" crashes after trying above fixes, don‘t fret. We have additional aces up our furry sleeves!

Here are bonus tweaks and setting changes reported to banish crashes for good:

Run Steam/Game as Administrator – Overrides limited user access potentially blocking game files

I recommend methodically testing each tweak above one by one until discovering your unique crash culprit.
