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
