1. Create Class

<Reflection.DefaultMember("Value")>
Public Class IntegerRange
    Private ReadOnly _anyOf() As Integer
    Private _range? As (Start As Integer, [End] As Integer)
    Private _value As Integer

    Public Sub New(value As Integer, anyOf() As Integer)
        _anyOf = anyOf
        Me.Set(value)
    End Sub

    Public Sub New(value As Integer, range As (Start As Integer, [End] As Integer))
        _range = range
        Me.Set(value)
    End Sub

    Public Sub New(range As (Start As Integer, [End] As Integer), anyOf() As Integer)
        _range = range
        _anyOf = anyOf
        Me.Set(_value)
    End Sub

    Public Sub New(anyOf() As Integer)
        _anyOf = anyOf
    End Sub

    Public Sub New(start As Integer, [end] As Integer)
        _range = (start, [end])
    End Sub

    Public Sub New(start As Integer, [end] As Integer, anyOf() As Integer)
        _range = (start, [end])
        _anyOf = anyOf
    End Sub

    Public ReadOnly Property Value As Integer
        Get
            Return _value
        End Get
    End Property

    Public Sub [Set](n As Integer)
        If _anyOf?.Contains(n) Then
            _value = n
            Return
        End If

        If _range.HasValue AndAlso n >= _range.Value.Start AndAlso n <= _range.Value.End Then
            _value = n
            Return
        End If

        Throw New ArgumentOutOfRangeException(NameOf(n))
    End Sub

End Class

2. Right Click on class name and select Quick Action, Generate Equal(Object)
3. Select Value uncheck the rest (may not be neccessary), then OK, you get a crash
   4 Enable and repeat but select nothing on first list but check either or both of the bottom check boxes the OK, you get a crash

Expected Behavior:
All the items get generated

Actual Behavior:
CheckDeclarationNode expects a block but it is called with a ClassStatement.

System.ArgumentException : Destination type must be a TypeBlockSyntax, CompilationUnitSyntax or NamespaceBlockSyntax, but given one is ClassStatementSyntax.
