How to Fix Unreal Engine 4 Crashing on PC

Unreal Engine is a popular game engine that developers employ to build and design games. As a suite, it has some of the best-integrated tools. However, when using Unreal Engine 4, various issues may arise. One of them is crashing. Thousands of players have recently reported the very same issue. But the good news is that you can fix it. In today’s article, we will find out a list of solutions that have proved useful to many players.

We advise that you begin with the first fix on the list. If the first procedure fails to do enough, then you can move on to the next solution and continue with the rest in that order until the problem gets resolved.

1. Update your Unreal Engine 4

Developers of Unreal Engine keep releasing new versions, so check if you have the latest version and install one if not. It’s the simplest fix to solve your crashing problem.

1) Open the Launcher, click the Unreal Engine tab, then go to your library Tab.

2) At the top you should see Engine Versions, and click the small down arrow to make sure you have the most recent one installed.

3) If there is a new version available, select the latest version and click Install.

Once it is installed, you can see if everything works fine for you. Hopefully, it does. But if not, there are still a few fixes to try.

2. Update your GPU driver

The crashing error may occur if the graphics card is outdated or corrupted. According to many users, updating drivers can always solve their problems. It can fix bugs and improve gaming performance and experience.

There are two ways you can update your video card drivers:

Manually – To update your graphics driver to the latest version, you’ll need to visit the manufacturer’s website, download the exact driver, and then install it manually.

Automatically – If you don’t have the time, patience or computer skills to update your drivers manually, you can, instead, do it automatically with Driver Easy. Driver Easy will automatically recognize your system and find the correct drivers for your graphics card, and your Windows version, and it will download and install them correctly:

1) Download and install Driver Easy.

2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click the Update button next to the flagged graphics driver to automatically download the correct version of that driver, then you can manually install it.

3. Verify the installation

Verifying the installation files can sometimes fix crashing issues. If you have Epic Launcher on your PC, you can use the built-in tool to check for corruption within the installed files.

1) Open the Epic Launcher.

2) Click the Library Tab, then click the small down arrow to expand the drop-down list. Click Verify.

3) Wait for the scans to complete. After the verification, the launch option appears. Click Launch.

See if this fixes your problem. If not, don’t worry, try the fix below to solve your problem.

4. Stop overclocking

In order to improve the gaming experience, you might have adjusted your GPU/CPU settings to the highest mode. However, this will lead to excessive energy consumption which may cause the crash.

So if you’re overclocking, you can try to set your CPU clock speed and GPU specifications back to the default. Many users find it helpful after doing so.

Also, turning down all the graphics settings to the lowest possible can help your Unreal Engine run smoothly.

If this fixes your crashing issues, congrats! But if not, you can try the next fix.

5. Change your default graphics card

Is there an Unreal Engine is existing due to D3D device being lost warning on your screen? In this case, the problem may be caused by your integrated graphics card for its limited performance.

If you have a dedicated graphics card installed on your PC, you can set your dedicated graphics card as the default graphics card to fix this error.

1) On your screen, right-click, and select NVIDIA Control Panel.

2) Click Manage 3D settings.

3) Under the Global Settings tab, select High-performance NVIDIA processor in the drop-down list. Finally, click Apply.

4) Restart your PC, then see if the problem is solved. If not, you can try the next fix.

6. Repair your system files

Unreal Engine crashing can be caused by missing or corrupt system files. To fix it, you might want to use a repair tool to check various areas in your computer to determine the cause of Surface Pro 7 screen flickering. It will deal with issues related to system errors, critical system files and find the right fix for you.

Reimage (commonly known as Reimage Repair) is a computer repair software that can diagnose problems on your computer and fix them immediately.

It will firstly check hardware-related issues to identify problems, and then security issues (powered by Avira Antivirus), and finally it detects programs that crash, missing system files. Once complete, it will find a solution to your specific problem.

1) Download and install Reimage.

2) Open Reimage and run a free scan. This might take 3~5 minutes to fully analyze your PC. Once complete, you will be able to review the detailed scan report.

3) You’ll see the summary of detected issues on your PC. Click START REPAIR and all the issues will be fixed automatically. (You’ll need to purchase the full version. It comes with a 60-day Money-Back Guarantee so you can refund anytime if Reimage doesn’t fix your problem).

7. Disable your antivirus temporarily

The Unreal Engine 4 crashing problem is sometimes caused by interference from your antivirus software. To see if that’s the problem for you, temporarily disable your antivirus program and check if the problem persists. (Consult your antivirus documentation for instructions on disabling it.)

If your game works properly after you disable the antivirus software, contact the vendor of your antivirus software and ask them for advice, or install a different antivirus solution.

Note: Be extra careful about what sites you visit, what emails you open, and what files you download when your antivirus is disabled.

If the crashing issue happens again, you can try to reinstall your Unreal Engine to fix your crashing issue.

8. Perform a reinstalling

Many people find a clean reinstalling can fix the problem. Just make sure you clear everything (including registry entries) assigned to Epic Launcher and Unreal Engine 4.

Note: Don’t forget to back up your projects before reinstalling.

After completing installing, see if your issue still persists.
