5.3 crashing. Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0xffffffffffffffff

LordMisterMan · October 19, 2023, 3:41am

Unreal 5.3.1 keeps crashing. I’m unable to reliably reproduce it with a specific action, but it crashes at minimum 30 seconds after loading my level, at most 5 minutes after. Actions that have triggered it include moving around (in both play and edit modes) painting foliage, painting landscape textures, and placing blueprints onto the landscape.

I started getting the

I’ve tried restarting my pc, updating graphics drivers, uninstalling all 3rd party plugins, migrating the level to a new project, deleting saved and intermediate folders, fully re-installing the engine, deleting all landscape tiles that weren’t absolutely necessary, fixing all redirectors, validating all assets, and some random regedit tips I found. Thus far, nothing has changed.
I’ve only used blueprints, and written no lines of c++ for this project.

Here’s my callstack. It’s the same for every crash

Same here, no idea where this crash is coming from. Started after a clean install of 5.3.1 in my machine. Any update let us know.

TanKrill326 · October 21, 2023, 1:14pm

After a lot of trial and error I was able to fix the issue. Not sure what it was specifically but disabling Lumen and removing all Fog components from the map fixed the crash.

LordMisterMan · October 22, 2023, 11:16pm

THE FOG!!

Thank you so much! I left lumen, but deleted the fog and the crashing has gone away.

When I was tracing through the source, it looks like the memory access that was causing the crash isn’t included in a release build, so hopefully I’ll be able to add the fog back right before I build.

I’ll post back with whether or not it works.

Hi all,

Has anyone had any luck in pinpointing this?
I removed the fog and lumen is not active but my project keeps crashing on start up.

I tried a couple of different proposed solutions but none have worked so far:

Updated Nvidia drivers
Verified Unreal (5.3.2)
Removed Fog / Made sure Lumen is not active
Reset Nvidia settings to default in the control panel

The next thing will be to set it up on my laptop, provided it can even manage the engine to see if it crashes there as well or if it is anything related to my hardware and some of the new logic. Old versions of the project do work still it seems to have happend in tandem with Structure Change results in Unknown structure error on build

Hi all,

Quick update from my side, i managed to fix this it had nothing to do with NVIDIA or Fog or anything like that in my case as far as i can gather.

I copied an existing structure to reuse for another use case and this seems to have broken the referencing structures and/or data tables.

What i did was empty the structure again recopiling everything, that worked and then i readded the rows back in one by one and now it seems to work fine i can cook again without error.

Hope this helps
Kind Regards

Maltewo · February 5, 2024, 1:01am

Thanks for the info! When talking about “structure” and “rows”, do you meancopying assets and folders from another project?

Holyfrog848 · February 13, 2024, 4:12pm

Not from another project but the same and i mean the structure class in the blueprint version of the engine.
Like this:

just copying this for example and referencing the copy along the original with a slightly altered name in a third structure broke it for some reason.

Luckhurst1 · April 28, 2024, 2:54pm

sry,my english bad.
I check my structure, and they are all correct compilation.
But,5.3 still crash.
I don’t konw why or maybe i can’t Understand what do you do

I managed to fix this bug after disabling virtual textures (project settings).

Holyfrog848 · June 22, 2024, 12:17pm

I encountered this again with 5.4.2, now i get it pretty much every time i change any of my actor components and then try to simulate.
This is very unfortunate as i have to say, i do not see me developing anything in the enging with these crashes all the time, very frustrating.

In case anyone encountered it before and was able to find out where it comes from i would be very grateful.

I’m using 5.4 and I just got this error today.

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0xffffffffffffffff

Managed to narrow it down to an actor component that had a bad reference in my blueprint. I had changed a Text array variable to a Data Structure array variable, which necessitates updating the related dependencies. While the engine is pretty good at alerting me when I have an invalid type connection, this one slipped through and I was somehow able to compile anyway without errors.

Long story short, check all your connections and make sure the in and out pins match type.

Hello guys, I encountered this error too.

My case was during foliage mesh deleting process for optimization.
I was deleting not using foliage meshed suddenly unreal engine crashed.

So I tried to reboot the engine but the same error massage poped up when I tried to open the world level.
Then,

I check the meshes that I originally deleted when engine crashed.
I deleted those meshes cause I was not gonna use
Problem solved, I was able to load the original level that has crashed.

I slightly doubt that the cause was level mesh information was different because it has crashed.
But honestly I donno, there seems to be lot’s of probable causes.

Moon_Patrol_1 · October 9, 2024, 7:23pm

My project would crash on launch. Ended up navigating in file explorer to the content folder where the structure asset was that I duplicated, and I deleted it. After that I was able to launch project again. Thanks for the advice, will now just create new struct instead of duplicating it.

slayer77 · October 26, 2024, 5:32pm

I changed Only the default RHI to DX11 in the project setting,
I had hardware ray tracing enabled in the project. it stays the same, nothing changed visually.

vmladin · November 12, 2024, 3:40pm

Rolling it back to DX11 fixed my issue as well

jhonut · November 15, 2024, 5:28pm

Same here, I am not sure what is causing that, I dont have any blueprints, any structs any fancy stuff I just try to render some stuff. No dev is looking into this matter?
