Hi ryuikuya,

This might be a known issue that we are working to resolve (for internal reference, UE-20210). To help us determine if you are experiencing the same issue, can you please copy the Callstack that is provided when the crash occurs?

Thank you.

I’m experiencing a crash in 4.18 on triggering the SetCurrentLanguageAndLocale blueprint node in PIE mode. The main thread asserts because an FSlateTextLayout’s lineview array has changed during iteration. Is this the same issue?

Abbreviated call stack:

UE4Editor-Slate.dll!FSlateTextLayout::OnPaint(const FPaintArgs & Args, const FGeometry & AllottedGeometry, const FSlateRect & MyCullingRect, FSlateWindowElementList & OutDrawElements, int LayerId, const FWidgetStyle & InWidgetStyle, bool bParentEnabled) Line 72 C++ Symbols loaded.

Hi Chris.

This original post is from over two years ago, on the 4.9 engine release, so things have definitely changed and you are almost certainly experiencing a different issue.

We also have a new process for reporting bugs now. Please fill out the bug submission form and our support staff can investigate the report. Unreal Engine Bug Submission Form - Formstack

Thanks
