What Causes Wuthering Waves Crashing on PC?

When you are playing on a desktop or laptop, Wuthering Waves crashing is rarely related to your actual personal account or save data. Instead, it means that the game’s core engine is fundamentally at odds with your hardware, your graphics drivers, or your background security software. Here is how to identify and fix three of the most severe PC launch errors.

What is the UE4 Fatal Error?

The Unreal Engine 4 (UE4) fatal error is one of the most notorious roadblocks for PC players. What causes this error? It occurs when the game launcher tries to boot but hits a corrupted core file or your graphics card rejects the default rendering engine. Since the game relies heavily on the UE4 architecture and even a single kilobyte of data missing from a recent update can cause Wuthering Waves to crash immediately.

How to Fix the UE4 Fatal Error?

If you are stuck at the UE4 prompt, here is how to force the game to bypass the broken launch sequence discussed below.

1. How to check client files: Open the official Kuro Games launcher. Click the wrench icon in the top right corner and select Repair. his will force the launcher to scan your local folder and replace the specific corrupted file that is causing UE4 to block.

2. How to Force DirectX 11: If the repair tool fails, your GPU may be rejecting DirectX 12. Add Wuthering Waves as a “Non-Steam Game” to your Steam library (select Client-Win64-Shipping.exe file). Right click the game in Steam and open Properties, and type -dx11 in the Launch Options box. Launching through Steam will now force the older ultra stable rendering engine.

What Causes the Anti Cheat Expert (ACE) Blue Screen of Death?

A Blue Screen of Death (BSOD) is the worst case scenario for Wuthering Waves to crash and it forces you to restart your entire computer. What causes a BSOD here? Actually, The game uses a kernel level security program called Anti Cheat Expert (ACE). If this anti cheat software conflicts with your Windows security permissions or third party antivirus, Windows will panic and crash the entire system to protect itself.

To prevent ACE from triggering a system failure, you must increase its permissions.

1. How to run as administrator: Right click on your Wuthering Waves desktop shortcut and select “Run as administrator“. This will give ACE software the permissions it needs to run without disabling Windows Defender.

2. How to whitelist the game: Very first thing is, Open your Windows Security settings or your third party antivirus application and add the entire Wuthering Waves game folder to your “Exclusions” or “Whitelist” settings.

What to Do When GPU Drivers Cause Random Freezing?

Sometimes the game will start perfectly, but completely freeze your display during combat and requesting you to use “Task Manager to stop the process“. What’s going on here? This particular type of Wuthering Waves crashing is currently related to faulty graphics drivers, specifically recent updates from NVIDIA and AMD that aggressively throttle the game’s asset loading.

How to Roll Back Your Graphics Drivers

1. How to roll back NVIDIA/AMD drivers: First, Open your Windows Device Manager and expand Display Adapters. Now, right click your graphics card, and select Properties. Under the Driver tab, click Roll Back Driver to “revert” to an older and more stable version.

2. Alternative method: If the roll back button is grayed out, visit the official NVIDIA or AMD website. Now, manually download an older and proven driver version (such as NVIDIA 566.36), and perform a clean installation again.

What Causes Wuthering Waves Crashing on Mobile?

Mobile devices handle memory rendering differently than desktop computers. If Wuthering Waves is crashing on your smartphone or tablet, it is usually related to temporary data conflicts. And processor incompatibility (particularly on some Samsung devices), or aggressive RAM management by your phone’s operating system.

What is the Mobile Black Screen Error?

Many players report that when they tap the app icon, they get an endless and dark display instead of the login screen. What triggers this black screen? Unlike PC bugs, this particular form of Wuthering Waves crashing is almost always a memory caching issue.When Kuro Games rolls out a hotfix, your Android or iOS device will attempt to load the new patch using old and temporary cached data. This data conflict will result in a complete failure to render the game.

How to Fix the Mobile Black Screen Issue

To stop Wuthering Waves crashing right at the Kuro Games logo, you will need to remove the corrupted temporary data.

1. How to clear Android cache: Mainly, Navigate to your phone Settings and then choose Apps. Now select Wuthering Waves App and go to Storage. Tap Clear Cache. (Warning: Do not tap “Clear Data” unless you are willing to redownload the entire 15GB+ game, otherwise entire data will be gone)

2. How to reset iOS memory: Since iPhones don’t have a dedicated cache clearing button, you have to swipe up to completely, so close the app from your multitasking view. After closing it, perform a hard system “restart” on your iPhone or iPad to dump any corrupted RAM.

What Causes Wuthering Waves Crashing During Cutscenes?

You may find that the game runs perfectly while you are exploring, but as soon as a major story cutscene plays, the app abruptly closes. What’s going on here? This type of Wuthering Waves crashing is usually caused by hardware overheating or a feature called “RAM expansion” on modern Android phones. Virtual RAM expansion in Unreal Engine mobile games often causes severe lag in stuttering, causing the application to freeze.

How to Stop Mobile Cutscene Crashes

1. How to disable RAM expansion (Android): Go to your phone’s main settings, search for “RAM expansion” or “virtual RAM,” and turn this feature “off“. Restart your phone before starting the game again.

2. How to Prevent Overheating Shutdowns: First, Open the in game settings, navigate to Graphics, and lower your resolution and framerate to “30 FPS”. Overheating of any phone is a primary cause of Wuthering Waves crashing on mobile, as phones will automatically force close heavy applications to protect their internal batteries.

Sometimes, a sudden game crash can corrupt your active session data and that causing severe network pipeline issues when you try to reload the game. If your game has stopped crashing but you are now stuck on loading screens with a server failure warning, see our guide on how to bypass the [Wuthering Waves Gateway Connection Timed Out] error screen.
