UEFN Keeps Crashing [Blocker]

Hello! I have loaded up the Unreal Editor and it was going smooth, But once I enabled “Performance Mode”. It keeps crashing when I try to load up any projects.

I have tried Uninstalling then reinstalling Fortnite and that has not fixed the issue.

Hello! I’m not able to repro your crash via setting preview to performance mode. But if you want to un-set this as it’s causing crashes (and you can’t access this from the editor due to crashing) you can do so by going to this file:

AppData\Local\UnrealEditorFortnite\Saved\Config\WindowsEditor\EditorPerProjectUserSettings.ini

And deleting the added preview settings… ie these:

This should remove the setting and UEFN will go back to whatever your devices default previewing was. Feel free to post your device’s specs as that may help us reproduce this error and look into an actual fix in the future :slight_smile:

I GET THE SAME MESSAGE TOO. On startup, it says that entire dialog, and it doesn’t even show any apps being opened besides the crash reporter.

Yeh

Hello!, I am still unable to load into UEFN since the latest update. I am also getting the same error as before. I have also sent you a message with my logs.

Hi! I’m still experiencing this issue after the latest update.

Did anyone find a fix for this yet? I recently got locked out of my project because of this error and due to having it set to ‘open last project on startup’ I can’t access any other projects either.

i have this same issue too any fix yet??
