ConstructorHelper is in constructor but still won't work

Hello!
I’m making a plugin to handle landscape proxies, for this im implementing a class “Tile” Which is supposed to store date appropriate for each proxy. I would like to have a default material which I have already created, what I have so far looks like this:
.h


#include "CoreMinimal.h"
#include "LandscapeStreamingProxy.h"

//Creating material
#include "Runtime/CoreUObject/Public/UObject/ConstructorHelpers.h"

class PROCEDURALWORLD_API Tile
{
public:
	Tile();
	Tile(TObjectPtr<ALandscapeStreamingProxy> inProxy);
	~Tile() = default;


	TObjectPtr<ALandscapeStreamingProxy> streamingProxy = nullptr;
	UMaterial* myMaterial;

.cpp

Tile::Tile(TObjectPtr<ALandscapeStreamingProxy> inProxy)
{
	streamingProxy = inProxy;
	
	static ConstructorHelpers::FObjectFinder<UMaterial> Material(TEXT("Material'/Game/Test_assets/M_grassMaterial.M_grassMaterial'"));

	if (Material.Object != NULL)
	{
		myMaterial = (UMaterial*)Material.Object;
		UE_LOG(LogTemp, Warning, TEXT("Value tx: %s"), *myMaterial->GetName());
		
	}

	
}

However, when I try to create Tiles the engine crashes and the message I get is that FObjectFinders can’t be used outside of constructors.

What am I doing wrong here?

Read that for Slate, COnstructorHelpers won’t work, I solved it by using LoadObject instead.

UMaterial* temp = LoadObject<UMaterial>(nullptr, TEXT("Material'/Game/Test_assets/M_grassMaterial.M_grassMaterial'"));

if(temp)
{
myMaterial = temp;

}
