System.ArgumentNullException: Value cannot be null. (Parameter 'key')

1. Describe the bug I've encountered an error on the CodeCop while working in AL. The error occurs when leaving out the ; at the end of line 7.

Analyzer 'Microsoft.Dynamics.Nav.CodeCop.Design.Rule228DoNotDeclareUnusedLocalMethods' threw an exception of type 'System.ArgumentNullException' with message 'System.ArgumentNullException: Value cannot be null. (Parameter 'key')
   at System.Collections.Generic.Dictionary`2.FindValue(TKey key)

A clear and concise description of what the bug is.

2. To Reproduce Create an empty project an create the AL code below, without the ; at the ending of the IF-statement line.

codeunit 50100 MyCodeunit
{
    local procedure MyProcedure()
    var
        Rec: Record "Warehouse Entry";
    begin
        if Rec."Reference Document" >= Rec."Reference Document"::"Posted P. Inv." then
    end;
}

Note: Because the developers need to copy and paste the code snippet, including a code snippet as a media file (i.e. .gif) is not sufficient.

5. Versions:

• AL Language: v13.0.897376
• Visual Studio Code: 1.84.2
• Business Central: 23.1.13431.14020
