Calling a class constructor in an automation test prevents me from opening my project

I’ve been trying to open my project, and it consistently crashes at 79%.

This is the most relevant part of the log file that I have:

I’ve already tried deleting my Saved and Intermediate folders, restarting my computer, ,regenerating visual studio project files, and rebuilding the project from inside visual studio. None of those have worked.
I also can’t revert to a previous version using source control, since I only back up the Source folder. However, I do have a previous version of the Source folder that contains code that didn’t make the project crash.

EDIT: I now know that the problem is this automation test, which simply calls the constructor of my Grid class

#include "Grid.h"
#include "AutomationTest.h"

IMPLEMENT_SIMPLE_AUTOMATION_TEST(FConstructionTest, "GridTest.Grid.Constructor Test", EAutomationTestFlags::EditorContext | EAutomationTestFlags::SmokeFilter)
bool FConstructionTest::RunTest(const FString& Parameters)
{

	//Construct a AGrid object. When this line is uncommented, my project fails to open
	//AGrid TestGrid;

	//TODO: Stuff

	return true;
}

The source code of the AGrid class can be seen here. This class is a superclass that is used to create square grids and hex grids. Also, the same problem of calling the constructor applies to any class that inherits from AGrid:

---GRID.H---#pragma once#include "CoreMinimal.h"#include "Runtime/Core - Pastebin.com

Commenting out the line which calls the constructor of AGrid allows me to open my project again, but it also means I can’t run tests on my classes. Is there something I’m missing in my code?
