[ERROR] UE 5.3.2 Crashed : EXCEPTION_ACCESS_VIOLATION ?

Development Getting Started & Setup
1

Hello everyone!

I’ve been using Unreal Engine (5.3.2) for several months now and haven’t had any problems using it (very few anyway).

I took a break from using it for about a month, and yesterday I resumed my project. But for some reason, U.E5 crashes every minute I use it.

Here’s the pop-up window after the application suddenly closes:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x000004ef7af2be78

ntdll

I used DDU Completely to cleanly reinstall my graphics card and its updates, reinstalling U.E on an SSD the problem is still the same.
Same with a new project.

I’m so sad that I can’t do anything, I find it exciting to learn Unreal Engine and I really want my project to progress step by step.

If anyone can help me solve this, thank you very much.

Config : (It hasn’t changed since I first used Unreal).

WIN 10-64x
AMD FX 8350 8core 4ghz
RAM 32go
Nvidia GTX 1060 6gb

Thank you !

Do newly created projects also crash?

Try opening from the explorer rather than the Unreal launcher, that solved the issue for me. Also did you try disabling any new plugins you might have installed?

Hi, yes i have the same problem with new projects !

Hi, yes, I’ve tried to run it with Win Explorer too, i’ve removed Quixel Bridge (the only plugin i have), always the same with new projects too.

Example: I perform a task like importing files, or browsing the interface, it happens.

It could still be related to your GPU driver:

Hi , why is this happening when i’ve been working on it for several months without this problem?..

I changed the RHI “DX12” to “Default”, Unreal seems more stable now, is it DX12 that’s causing the problem after all?..

I really don’t understand what could have happened in a few weeks break… It’s weird…

Hello everyone,

After resuming my project in Unreal Engine (5.3.2), I’ve been experiencing frequent crashes with the error “EXCEPTION_ACCESS_VIOLATION.” I’ve tried reinstalling graphics drivers and Unreal Engine on an SSD, but the issue persists. Any help would be appreciated. Thank you!

Having same issue in UE 5.5. I’m running AMD Ryzen 9 with RTX 3060 on Zephyrus G14 laptop Windows 11. If I change the RHI to DX11 the problem stops. It only happens with DX12 and crashes most frequently if using Tessellation and Nanite with Materials. Crashes most frequently in the Material Graph Editor.
