@SenSeiVisual I’m sorry you’re encountering this. We’ve noticed this issue is affecting you and a small subset of users, but we haven’t yet been able to reproduce it and could use your help with some contextual information to narrow it down.

  • Are you working solo or on a team?
  • If you are on a team, have your teammates hit the crash as well or is it only happening to you/certain individual accounts
  • Did you have UEFN configured to “Open Last Project on Start Up”?
  • Could you share your local editor settings file with me so we can see if there is anything changed from common defaults that may be causing this? The file should be found at C:\Users\[USERNAME]\AppData\Local\UnrealEditorFortnite\Saved\Config\WindowsEditor and the file is called EditorPerProjectUserSettings.ini - feel free to DM it to me on discord at EPIC_garren

I am having a very similar issue. My error is; Fatal error!

I do not even get to the templates. It starts to load the template screen and crashes before the projects show up. Unreal Editor (regular) launches normally, UEFN crashes.

@devil_dog1 I’m sorry you’re running into it too. We’d be very interested for you to answer the questions I posted above as well.

SOLO, NO

I sent you a friend request from “berean” to send you a dm with the file.

I was able to get back in by deleting that file you requested. :slight_smile: thank you!

Ah that’s great news @devil_dog1 - by any chance did you save a copy of it before deleting it, so you can send it over to us? It’ll help us identify what about it was causing this issue. I accepted your the friend request

I’m experiencing the same crash but removing EditorPerProjectUserSettings.ini doesn’t help. Happy to send over answers to the questions above as well as the file via Discord. I send a friend request

having the exact same issue, wont even launch.

  • Are you working solo or on a team? SOLO
  • If you are on a team, have your teammates hit the crash as well or is it only happening to you/certain individual accounts? NOT ON TEAM
  • Did you have UEFN configured to “Open Last Project on Start Up”? It does not open last project
  • Could you share your local editor settings file with me so we can see if there is anything changed from common defaults that may be causing this? The file should be found at C:\Users\[USERNAME]\AppData\Local\UnrealEditorFortnite\Saved\Config\WindowsEditor and the file is called EditorPerProjectUserSettings.ini - feel free to DM it to me on discord at EPIC_garren I can share, but i tried deleting like above and it did not fix the issue

**EDIT: deleted the App data folder for UEFN
and it fixed the issue

As some folks have mentioned here and in other topics, a reliable path for resolving the crash is to reset all local user and editor settings.

Disclaimer: While this will stop the editor from crashing and preserve all of your core project data, you will lose any local editor customizations and settings you’ve made (such as the layout of editor windows) and some data cached for your convenience (such as your project panel being sorted by most recently accessed) will be reset.

If you’d like to proceed with this path, please take the following steps:

  1. Open Windows File Explorer
  2. Paste C:\Users\[USERNAME]\AppData\Local\UnrealEditorFortnite\ into the address bar and replace “[USERNAME]” with your windows account username
  3. Press “Enter” to navigate to the folder
  4. Create a zipped copy of this folder to your desktop to back it up (just in case of any issues)
  5. After the backup is complete, delete the contents of the folder
  6. Attempt to relaunch the editor

Please let us know if this works for you!

I tried it, didn’t work still have crash.

@Amanda.Schade Can you please get ahold of me and walk me through this, I’ve tried and can’t find the file. Could you DM me on discord @ELUSORYCHIEF7#6835

@speedgate not sure if Amanda already got ahold of you, but the AppData folder is generally hidden by default, which means you wont see it browsing for it manually, but can navigate to it directly with the filepath provided above. Steps to do this:

  • open Windows File Explorer
  • paste the path (C:\Users\[USERNAME]\AppData\Local\UnrealEditorFortnite) into the address bar of that window
  • Replace “[USERNAME]” with your windows username
  • Press “Enter”

This should take you to the direct location of that folder so you can proceed with the steps provided.
