Hello UE4 community.
I’ve been trying to fix a problem with editor crash. It occurs when I try to click on my custom plugin in editor modes. The delegates in SEditableTextBox seem to be the problem because when I comment them out everything works but no idea why. Here’s the code:

GridToolsEdModeToolkit.h

FText GetRadius() const;
void SetRadius(const FText& InText);
static int32 Radius;

GridToolsEdModeToolkit.cpp

int32 FGridToolsEdModeToolkit::Radius = 0;

FText FGridToolsEdModeToolkit::GetRadius() const
{
	FText myText = FText::FromString(FString::FromInt(Radius));
	return myText;
}

void FGridToolsEdModeToolkit::SetRadius(const FText& InText)
{
	FString tempString = InText.ToString();
	Radius = FCString::Atoi(*tempString);
}

SAssignNew(ToolkitWidget, SBorder)
		.VAlign(VAlign_Top)
		.HAlign(HAlign_Center)
		.Padding(5)
		.IsEnabled_Static(&Locals::IsWidgetEnabled)
		[
			SNew(SVerticalBox)
			+ SVerticalBox::Slot()
				.VAlign(VAlign_Top)
				.HAlign(HAlign_Left)
				.Padding(5)
				[
					SNew(STextBlock)
					.AutoWrapText(true)
					.Text(LOCTEXT("TLabel", "T - Toggle tiles"))
				]
			+ SVerticalBox::Slot()
				.VAlign(VAlign_Top)
				.HAlign(HAlign_Left)
				.Padding(5)
				[
					SNew(STextBlock)
					.AutoWrapText(true)
					.Text(LOCTEXT("ELabel", "E - Enable tiles"))
				]
			+ SVerticalBox::Slot()
				.VAlign(VAlign_Top)
				.HAlign(HAlign_Left)
				.Padding(5)
				[
					SNew(STextBlock)
					.AutoWrapText(true)
				.Text(LOCTEXT("DLabel", "D - Disable tiles"))
				]
			// SEditableTextBox
			+ SVerticalBox::Slot()
				[
					SNew(STextBlock)
					.Text(LOCTEXT("SEditableTextBoxLabel", "SEditableTextBox"))
				]
			
			+ SVerticalBox::Slot()
				.HAlign(HAlign_Left)
				.Padding(0.0f, 5.0f)
				[
					SNew(SEditableTextBox)
					.HintText(LOCTEXT("SEditableTextBoxHint", "Radius"))
					.Text(this, &FGridToolsEdModeToolkit::GetRadius)
					//.OnTextChanged(this, &FGridToolsEdModeToolkit::SetRadius)
				]
		];
