I am trying to make a custom GameUserSettings class inside of a plugin, coded it and modified DefaultEngine.ini to use my custom class instead of the default one. Now I get this error whenever I try opening my project:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000240

my source code for the infringing methods is this:

void UJF_GameUserSettings::ApplySettings(bool bCheckForCommandLineOverrides) {
	Super::ApplyNonResolutionSettings();

	ApplyAdvancedSettings();

	Super::ApplyResolutionSettings(bCheckForCommandLineOverrides);

	SaveConfig();
}

and this is ApplyAdvancedSettings:

void UJF_GameUserSettings::ApplyAdvancedSettings() {
	//Misc
	if (bEnableBloom) {
		GetWorld()->Exec(GetWorld(), TEXT("r.DefaultFeature.Bloom 1"));
	}
	else
	{
		GetWorld()->Exec(GetWorld(), TEXT("r.DefaultFeature.Bloom 0"));
	}

	if (bMotionBlur) {
		GetWorld()->Exec(GetWorld(), TEXT("r.DefaultFeature.MotionBlur 1"));
	}
	else
	{
		GetWorld()->Exec(GetWorld(), TEXT("r.DefaultFeature.MotionBlur 0"));
	}

	//Check for ray tracing
	if (bRayTracing && GRHISupportsRayTracing) {
		GetWorld()->Exec(GetWorld(), TEXT("r.RayTracing 1"));
	}
	else {
		GetWorld()->Exec(GetWorld(), TEXT("r.RayTracing 0"));
	}

	if (bRayTracing && ShadowsType == EShadowsType::RayTraced && GRHISupportsRayTracing) {
		GetWorld()->Exec(GetWorld(), TEXT("r.RayTracing.Shadows 1"));
	}
	else {

	}

	if (bRayTracing && AmbientOcclusionType == EAmbientOcclusionType::RayTraced && GRHISupportsRayTracing) {
		GetWorld()->Exec(GetWorld(), TEXT("r.RayTracing.AmbientOcclusion 1"));
	}
	else
	{
		GetWorld()->Exec(GetWorld(), TEXT("r.RayTracing.AmbientOcclusion 0"));
	}

	if (bRayTracing && ReflectionsType == EReflectionsType::RayTracing && GRHISupportsRayTracing) {
		GetWorld()->Exec(GetWorld(), TEXT("r.RayTracing.Reflections 1"));
	}
	else
	{
		GetWorld()->Exec(GetWorld(), TEXT("r.RayTracing.Reflections 0"));
	}

	if (bRayTracing && TranslucencyType == ETranslucencyType::RayTracing && GRHISupportsRayTracing) {
		GetWorld()->Exec(GetWorld(), TEXT("r.RayTracing.Translucency 1"));
	}
	else
	{
		GetWorld()->Exec(GetWorld(), TEXT("r.RayTracing.Translucency 0"));
	}

	switch (GIType)
	{
	case EGlobalIlluminationType::Off:
		GetWorld()->Exec(GetWorld(), TEXT("r.RayTracing.GlobalIllumination 0"));
		GetWorld()->Exec(GetWorld(), TEXT("r.SSGI.Quality 0"));
		break;

	case EGlobalIlluminationType::RayTraced:
		if (bRayTracing && GRHISupportsRayTracing) {
			GetWorld()->Exec(GetWorld(), TEXT("r.SSGI.Quality 0"));

			switch (RTGIType)
			{
			case ERayTracingGlobalIlluminationType::FinalGather:
				GetWorld()->Exec(GetWorld(), TEXT("r.RayTracing.GlobalIllumination 1"));
				GetWorld()->Exec(GetWorld(), TEXT("r.RayTracing.GlobalIllumination.EnableFinalGather 1"));
				break;

			case ERayTracingGlobalIlluminationType::BruteForce:
				GetWorld()->Exec(GetWorld(), TEXT("r.RayTracing.GlobalIllumination 1"));
				GetWorld()->Exec(GetWorld(), TEXT("r.RayTracing.GlobalIllumination.EnableFinalGather 0"));
				break;

			default:
				break;
			}
			break;
		}
		else
		{
			break;
		}

	case EGlobalIlluminationType::ScreenSpace:
		GetWorld()->Exec(GetWorld(), TEXT("r.RayTracing.GlobalIllumination 0"));
		GetWorld()->Exec(GetWorld(), TEXT("r.SSGI.Quality " + UKismetMathLibrary::Clamp(ScreenSpaceGIQuality, 1, 4)));
		break;

	default:
		break;
	}
}

this is what i included in the .cpp file:

#include "Misc/JF_GameUserSettings.h"
#include "GameFramework/GameUserSettings.h"
#include "AudioDevice.h"
#include "Engine/Engine.h"
#include "Kismet/KismetMathLibrary.h"
#include "RHI.h"

I am happy to provide more source code if it helps!
