Unity Editor crashes on running these scripts

Question

So, my editor keeps on crashing on running these scripts. Specifications of my pc(if needed): Intel i5,8GB ram,Windows 10

I am trying to make a Minecraft game and my editor crashes:

VoxelData.cs:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public static class VoxelData
{
    public static readonly int ChunkWidth = 2;
    public static readonly int ChunkHeight = 2;
    public static readonly Vector3[] voxelVerts = new Vector3[8] {
        new Vector3(0.0f,0.0f,0.0f),
        new Vector3(1.0f,0.0f,0.0f),
        new Vector3(1.0f,1.0f,0.0f),
        new Vector3(0.0f,1.0f,0.0f),
        new Vector3(0.0f,0.0f,1.0f),
        new Vector3(1.0f,0.0f,1.0f),
        new Vector3(1.0f,1.0f,1.0f),
        new Vector3(0.0f,1.0f,1.0f),
};
    public static readonly int[,] voxelTris = new int[6, 6]{
        {0,3,1,1,3,2},
        {5,6,4,4,6,7},
        {3,7,2,2,7,6}, // top face
        {1,5,0,0,5,4},
        {4,7,0,0,7,3},
        {1,2,5,5,2,6}

        };

}

and the Chunk.cs script:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Chunk : MonoBehaviour
{
    public MeshRenderer meshRenderer;
    public MeshFilter meshFilter;
    // Start is called before the first frame update
    int vertexIndex = 0;
    List<Vector3> vertices = new List<Vector3>();
    List<int> triangles = new List<int>();
    List<Vector2> uvs = new List<Vector2>();
    void Start()
    {

        for(int y = 0; y < VoxelData.ChunkHeight; y++)
        {
            for (int x = 0; x < VoxelData.ChunkWidth; x++)
            {
                for (int z = 0; x < VoxelData.ChunkWidth; z++)
                {
                    AddVoxelDataToChunk(new Vector3(x, y, z));
                }
            }
        }

        CreateMesh();

    }
     void AddVoxelDataToChunk(Vector3 pos)
    {
        for (int p = 0; p < 6; p++)
        {
            for (int i = 0; i < 6; i++)
            {
                int triangleIndex = VoxelData.voxelTris[p, i];
                vertices.Add(VoxelData.voxelVerts[triangleIndex] + pos);
                triangles.Add(vertexIndex);

                uvs.Add(Vector2.zero);

                vertexIndex++;
            }
        }
    }
    void CreateMesh()
    {
        Mesh mesh = new Mesh();
        mesh.vertices = vertices.ToArray();
        mesh.triangles = triangles.ToArray();
        mesh.uv = uvs.ToArray();

        mesh.RecalculateNormals();
        meshFilter.mesh = mesh;
    }
    // Update is called once per frame
}

why does it keep crashing, it is quite annoying and not letting me continue on this project. Please help and advise what to do

Try to catch an exception and look at its message.

The most inner

             // | here !
             // v 
for (int z = 0; x < VoxelData.ChunkWidth; z++)
{
    AddVoxelDataToChunk(new Vector3(x, y, z));
}

will cause an infinite loop since x is nowhere changed inside it.

It should most probably be z

             // | here !
             // v 
for (int z = 0; z < VoxelData.ChunkWidth; z++)
{
    AddVoxelDataToChunk(new Vector3(x, y, z));
}
