hi

the relevant bit of log is

Pure virtual function being called while application was running (GIsRunning == 1).
[175]LogOutputDevice: Warning:
Script Stack (0 frames) :
LogWindows: Error: appError called: Fatal error: [File:D:\build++UE5\Sync\Engine\Source\Runtime\Core\Private\Windows\WindowsPlatformMisc.cpp] [Line: 440]
Pure virtual function being called
LogWindows: Windows GetLastError: The operation completed successfully. (0)

This is maybe a windows error than UEFN

Maybe your logs have more mine just was processed through ue5 core dump reader

Same issues here. What I’ve noticed is that this is happening on all widget children widgets if the parent has this red exclamation mark with “Existing Widget Name”. The widget worked perfectly before the update, and also didn’t have that red exclamation mark.

Found a fix, you have to rename every widget that has that red exclamation mark with “Existing Widget Name”. I think they changed it in this update so you can’t have the 1:1 same name in the same WBP.
