This problem lies in YOUR PC in YOUR files and you are responsible for using this procedure.
The problem reported above can be fixed by clearing YOUR local temp file
which contains files going back to 29.60
Make sure you have restarted your PC
To fix this
download the UEFNfixRun2.txt file, confirm you do want to download this file to Windows Browser
UEFNfixRun2.txt (344 Bytes)
Type Windows key + R
In the box type “cmd”
Click ok, the windows batch console opens
type
cd %USERPROFILE%\downloads
ren UEFNfixRun2.txt UEFNfixRun.bat
now type UEFNfixRun.bat
You will see lots of files from old projects, potentially from 29.60, getting deleted
these files are causing conflicts with the latest UEFN from 30.00 onward
This area of pc is often hidden and cannot be seen in Windows File Explorer
The directories
UnrealEditorFortnite\Intermediate
and
UnrealEditorFortnite\Saved
are recreated when UEFN starts
The %USERPROFILE% is equivalent to C:\User\NAME where NAME is like OWNER
The commands are listed below
rem "C:\Users\OWNER\AppData\Local\UnrealEditorFortnite"
echo on
cd %USERPROFILE%\AppData\Local\UnrealEditorFortnite\C:\Users\jimgi\AppData\Local\UnrealEditorFortnite\Intermediate
del/s/q *.*
cd %USERPROFILE%\AppData\Local\UnrealEditorFortnite\C:\Users\jimgi\AppData\Local\UnrealEditorFortnite\Saved
del/s/q *.*
echo off
cd %USERPROFILE%
Restart UEFN 31.20 and open your project
The new Validation errors will cause the popup to occur
Click “Run” and you will see UEFN scanning for errors and attempting to fix them
If this does not run check the output log for RED texture error messages
AssetCheck: Error: /HandsApart/Quests/expQUEST_BORDER The height and width of this texture both need to be a power of 2 (for example, 128x256 or 512x1024) so that the texture can support streaming.
Its current size is 1920x1080. Adjust the source image so that both height and width are powers of two and reimport the asset.
To fix this automatically, right-click the asset and choose 'Conform Texture', or click 'Fix' below. (ValkyrieValidator_Textures) Fix: /HandsApart/Quests/expQUEST_BORDER
