C6385 c как исправить

This question is most likely common and has been asked before. So, after spending a mind-numbing 30 minutes trying to find the solution to what I believe is a false negative, I’m resulting to posting my issue here.

I’m relatively new to C++ Coding and figured I’d create a simple random item generator. Unfortunately, when grasping a random index in my arrays, I am given a c6385 error. This error usually pertains to an invalid or overloaded buffer from the research I’ve found. I believe this means that the index I’m trying to access is too large thanks to rand().

I will continue looking for a solution but would like some others’ opinions of the situation. I may be overlooking a small detail or am failing to grasp a concept. All help is greatly appreciated. If I come across a solution, I will lock/remove this to overpopulate the forums.

Here is my code:
ItemGeneration.h

#pragma once
#include <random>
#include <iostream>
using namespace std;

class ItemGeneration
{
public:
    /*
        Creating the cosntant variables for the items main effects.
        For instance, if you were to roll the main attribute of "Item1",
        this code would dictate what possible attributes that could be chosen.

        In addition to the main attributes, the code for the avaliable sub-attributes is also created below.

        Also creating the const array that hold the rarity of items.
        For instance, an item that rolls a higher weighted value will have a lower rating.
        More rare or 'uncommon' the value, the higher rating the item will recieve.
        Item rarity dictates the value of the attributes assigned to ie, i.e the higher the
        rarity the higher the attributes multiplier in addition to the number of sub-attributes.

    const char* Item1[4]
        = { "Attack %", "Health %", "Defense %", "Elemental Damage %" };

        = { "Mana Regeneration", "Cooldown Reduction", "Healing Efficacy", "Elemental Resonance" };

    const char* Item3[4]

        int randNum = rand() % 4 + 1;

** Update with errors **

I should have been more concise. However, I do not believe there to be an actual buffer error, a false negative.
As for the error messages.

My main function is returning a c2561 error, but I believe that to be a side effect of the item generation, not functioning. MEaning it simply is returning the value as the function isn’t operating.
Here is my terminal readout when attempting to build the solution:

C6385: Reding Invalid Data from 'this->item5'.

>Solution :

int main() {
   // stuff
   return;  // <- always an error
}

Here’s your problem. You promised that main would return an int, and then you reneged on that promise with just a plain return. main is a little special in that it should return an int, so, failing all else, make it return 0.

int main() {
   // stuff
   return 0; 
}

You did it again in ItemGeneration::ItemCreate

int ItemCreate(int x, int y) 
{
   // stuff
   return;    // nope
}

But in this case, there isn’t really anything to return. Your main routine ignores the return value anyway. So you should declare it to return void instead:

void ItemCreate(int x, int y) 
{
   // stuff
   return;    // OK now (not actually needed, however)
}
