Whenever you try to open the audit tools statistics window, UEFN crashes.
This happens even on brand new projects using built-in Empty Template.
Unreal Editor for Fortnite
UI/Tools
Open a project in UEFN
Click on the Tools menu from the hotbar
Click on Audit submenu
Click on Statistics submenu

Hi @OohWowow
This is a crash problem caused by a shortage of memory. Exception address 000xxx.
When a large manual virtual Memory page file is added, the crash does not occur.
The workaround would be to add a 64GB (64000 MB)
How to add a 64GB pagefile.sys manually
You may need a file with a capacity of even more than 128GB (128000), but it must reside on an SSD.
Some devs have a spare fast SSD drive allocated to just holding only this page file, but itâs much cheaper than another 128GB RAM!

The status of FORT-1019017 changed to âNeeds Triageâ. Weâve confirmed the issue and itâs waiting to be assigned to someone to fix it.

@OohWowow please attach the editor log when you report crashes, thereâs not much we can do without them. This crash does not reproduce in UEFN 38.11 with a simple island project.

Hi all,
Just tested on 38.11 with the UEFN Feature Example Alpha Tycoon, this function now works without an extra page file. The extra page file makes the UEFN project load 20% quicker on my pc, and UEFN 38.11 loads 20% quicker, just like the standard UE 5.7 Engine, which UEFN is based on.

@mihneabalta are you just looking for the editor log summary presented in the crash window as text?
even following the most-recent update, I am still seeing the Blank template crash when opening the audit tools. here is the summary I see
LoginId:c4cea4904ffc6752ff4e20a149b881fe
Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000030
UnrealEditorFortnite_Engine_Win64_Shipping
if there is another way to attach the rest of the log files, let me know and I will include them
Iâve been receiving this same error too, but happened randomly when I closed UEFN one time and then tried to open it. Iâm unable to access the project as of right now. Been having problems to load the umap too, strange.

I updated my virtual memory file to be 64GB as explained by this guide, but I am still seeing crashes on launching the audit tools

Hi @OohWowow ,
Your PC has from the logs âCreated a D3D12 device for NVENC on âNVIDIA GeForce RTX 5070â â.
There is an issue with drivers for RTX 50-series GPUs
RESOLVED: Known issues with NVIDIA 576.02 drivers on RTX 50-series GPUs | Epic Developer Community
If you donât want to update drivers the use DirectX 11.
To enable DirectX 11:
1. Open the Epic Games Launcher-d3d11 in the text field
8. Click ok and then launch as usual with Quick Launch
For Epic Support Engineers, the log message is
[2025.11.24-15.39.57:866][236]LogRenderer: Recreating Persistent SBTs due to initializer changes:
The crash message is
[2025.11.24-15.42.06:008][278]LogSlate: Warning: Slate: Had to block on waiting for a draw buffer
The above is a GPU rendering error . Last time, this was a DX12 (DirectX 12) error
The next lines are the crash data
[2025.11.24-15.42.08:781][278]LogWindows: Error: === Critical error: ===
My PC can ONLY use DX11, so thatâs why mine works

I updated my GPU drivers, and tried on both DX11 and DX12. Audit tools still cause crashes regardless.

hi @OohWowow ,
The only post that seems to cover these rendering crashes is
Any version crash!!! - Development / Programming & Scripting - Epic Developer Community Forums
Have you tried both NVIDIA Studio drivers AND NVIDIA Game drivers?
There are two sets, and before users found that one type worked with Unreal Engine 5 and the others did not.
Just have to wait for Epic Support. Sorry, itâs out of my depth now

hi @OohWowow
Just try my version of the blank audit tools project, unzip this project into
C:\Users\%USERNAME%\Documents\Fortnite Projects
Open UEFN
then open the project, UEFN will rant on about not being in UEFN - Content Service
and not the right Verse path etc, just keep clicking open
When open, go straight to Tools â Audit â Statistics
If it crashes, upload the latest log file so we can all look at this.

MyBlankForAuditTest.rar (53.7 KB)
Just looked at the look again. My Launcher/UEFN runs as Administrator

someone on our team was able to open audit tools without crashing. however, when they selected âActor Memory Statsâ from the dropdown, that DID cause the editor to crash.

deleting the folder contained at:
\AppData\Local\UnrealEditorFortnite
allows the audit tools to launch without crashing. however, trying to change the drop down option to âActor Memory Statsâ will cause a crash

Hi this fails on my UEFN 38.11@OohWowow started a new thread. Your team will need to vote this up to get this fixed, possibly[crash]UEFN Tools â Audit â Statistics ->Actor Memory Stats always Full Crash on Blank template - General / Issues and Bug Reporting - Epic Developer Community Forums
