Unknown errors in a SFML/C++ project (visual studio 2019 v.16.2):

I'm recently learning to make a 2d game in SFML using a tutorial series on youtube by Suraj Sharma(currently video 57):

After 10:14 into the video i receives a bunch of errors in the 'TileMap' class

Here's the code:

TileMap.h:

<pre>#pragma once
#ifndef TILE_MAP_HH
#define TILE_MAP_HH

#include "Tile.h"

class TileMap
{
private:
	float GridSizeF;
	unsigned GridSizeU;
	unsigned Layers;
	sf::Vector2u MaxSize;
	std::vector<std::vector<std::vector<Tile>>>Map;
public:
	TileMap();
	virtual~TileMap();

	//Funcs
	void Update();
	void Render(sf::RenderTarget& target);
};
#endif // !TILE_MAP_HH

TileMap.cpp:

<pre>#include "pch.h"
#include "TileMap.h"

TileMap::TileMap()
{
	this->GridSizeF = 50.f;
	this->GridSizeU = static_cast<unsigned>(this->GridSizeF);
	this->MaxSize.x = 10;
	this->MaxSize.y = 10;
	this->Layers = 1;

	/*Both push_back and resize functions have E0135 error
	which says:
		class "std::vector<std::vector<std::vector<Tile, std::allocator<Tile>>,

		std::allocator<std::vector<Tile, std::allocator<Tile>>>>>>"
		has no member "push_back"("resize")
		*/
	//E0020 : x,y,z are undefined
	//E0065 : expected a ';' in x,y,z for loop declaration

	this->Map.resize(this->MaxSize.x);
	for (size_t x = 0; x < this->MaxSize.x; x++)
	{				
		this->Map.push_back(std::vector<std::vector<Tile>>());
		for (size_t y = 0; y < this->MaxSize.y; y++)
		{	
			this->Map.resize(this->MaxSize.x);
			this->Map[x].push_back(std::vector<Tile>());
			for (size_t z = 0; z < this->Layers; z++)
			{	
				this->Map.resize(this->MaxSize.x);
				this->Map[x][y].push_back(Tile(x*this->GridSizeF, y * this->GridSizeF, this->GridSizeF));
			}
		}
	}
}

TileMap::~TileMap()
{
}

//Funcs
void TileMap::Update()
{
}

void TileMap::Render(sf::RenderTarget& target)
{
	for (auto& x : this->Map) {  /*E2291:this range-based 'for' statement requires
					 a suitable 'begin' function and none was found          
				     */
		for (auto& y : x) {
			for (auto& z : y) {
				z.Render(target);
			}
		}
	}
}

Before video 57 the project works perfectly fine.

Can anyone help me ?

What I have tried:

I've checked the precompiled header file in 'TileMap.cpp' and nothing is wrong.
