Editor crash when trying to compile data table code

I am trying to create a simple class for working with a CSV file in the editor. I have tried 4.11.2 and 4.10.4 and both crash when compiling the class. This is code from a book I am using to get familiar with the way Unreal does C++.

All of the code looks fine from what I can tell from scouring the documentation to see if I was doing something wrong.

TestCustomData.h:

#pragma once

#include "TestCustomData.generated.h"

USTRUCT(BlueprintType)
struct FTestCustomData : public FTableRowBase {
    GENERATED_USTRUCT_BODY()
    
    UPROPERTY(BlueprintReadOnly, Category = "TestCustomData")
    int32 SomeNumber;

    UPROPERTY(BlueprintReadOnly, Category = "TestCustomData")
    FString SomeString;
};

TestCustomData.cpp:

#include "RPG.h"
#include "TestCustomData.h"

When I go to compile this so I can import the CSV file the whole editor crashes and when I reload the project my newly created TestCustomData class is no longer present in the editor but the code is all still there in the project folders and such.

Is this a bug that has been there for numerous versions or am I doing something wrong?

If you need a reproduceable I can do that too.

I believe I figured out the issue. The book says to make the TestCustomData class an actor class then remove code. I went through and instead generated a Empty Class for FTestCustomData then manually added TestCustomData.generated.h to the header and removed the code + constructors from the cpp file and added my struct. It compiled fine and everything worked as intended. Figured I would put this here for others having the same issue.
