Movie Render Queue Crashes everytime with EXCEPTION_ACCESS_VIOLATION Error in Unreal Engine 5

Hello Unreal Engine Community,

I have been experiencing crashes when using the Movie Render Queue in Unreal Engine 5. My system has sufficient RAM and VRAM, and I’ve already updated my GPU drivers and verified my project files. The crash log shows the following error:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000003400000005

Here’s what I’ve tried so far:

Updated GPU drivers to the latest version.
Verified project files through the Epic Games Launcher.
Increased virtual memory.
Disabled third-party plugins.
Tested rendering in a new project.
Reinstalled Unreal Engine 5.

Despite these efforts, the issue persists. I would greatly appreciate any assistance or suggestions for resolving this problem.

Thank you in advance for your help!

I have exactly the same error. I am not sure but I think it started when I converted my map to a world partition map.

Hi to everyone, I’ve got the same problem.
When I render out… it crashes making this report:

Did you solve this issue yet???

So my issue started when I imported a 4.27 project over to 5.1 and tried to render said project map in 5.1 … when i went back to 4.27 and render it there – the render went perfectly so I’m not sure exactly what’s happening here

but Im going to convert the project instead and see if that works

Last week I was having crashes issues. Standard giant scene. Not sure what the error code was. At the time the geometry was not nanite because I was creating alpha masks with Stencil Layers. My issue was when I was rendering the backplate frames of the whole scene. Just to free up some V-ram I convert the geometry to nanite. Than I was able to render it and get the job out.
