Description

This is a common crash that has occurred since at least 4.17. Based on the user comment below, this may be a VR issue (unconfirmed)

User Descriptions

  • it seems to me UKismetMaterialLibrary::SetVectorParameterValue (....) many times, every frame May be implicated in the crash(?++ version). but Only in VR mode(HTC Vive). worked only helmet. I disabled the controllers, since I originally thought the problem was in them, but it turned out that they do not have any effect on this problem

Source Context

 1549       	// are given a chance to process accumulated values.
 1550       	ForEachUser([&] (FSlateUser* User) {
 1551       		const FWeakWidgetPath& WidgetPath = User->GetWeakFocusPath();
 1552       		for ( const TWeakPtr<SWidget>& WidgetPtr : WidgetPath.Widgets )
 1553       		{
 1554       			const TSharedPtr<SWidget>& Widget = WidgetPtr.Pin();
 1555       			if ( Widget.IsValid() )
 1556       			{
 1557 ***** 				Widget->OnFinishedKeyInput();
 1558       			}
