Copy Constructor / Dynamic Array / delete_scalar.cpp Error

Question

I create a program which enter a dynamic array of integer. I want to add a copy constructor, in order to become better acquainted with its functionality, but always when try to run program, Visual Studio open a new tab and get delete_scalar.cpp Error, so if anyone had a similar problem it would help me.

Here' s code:

DynamicArray.h

#pragma once
class DynamicArray
{
private:
    int* arr;
    int capacity;
    int number_of_elements;
public:
    DynamicArray(int capacity = 1);
    DynamicArray(const DynamicArray&);
    ~DynamicArray();
    void add(DynamicArray* arr, int value);
    void print(DynamicArray* arr);
};

DynamicArray.cpp

#include "DynamicArray.h"
#include <iostream>

DynamicArray::DynamicArray(int capacity): capacity(capacity),number_of_elements(0),arr(new int[capacity])
{}
DynamicArray::~DynamicArray()
{
    delete[] this->arr;
    this->arr = nullptr;
    this->number_of_elements = 0;
    this->capacity = 0;
}
DynamicArray::DynamicArray(const DynamicArray& other) : capacity(other.capacity),number_of_elements(other.number_of_elements),arr(new int[other.number_of_elements])
{
    
    for (int i = 0; i < number_of_elements; i++)
    {
        this->arr[i] = other.arr[i];
    }

}

main.cpp

int main()
{  
        DynamicArray obj(5);
    DynamicArray obj2(5);
    obj.add(&obj,22);
    obj.add(&obj,12);
    obj.add(&obj,18);
    obj.add(&obj,11);
    obj.print(&obj);
    obj2=obj;
    obj2.print(&obj2);
}

Error delete_scalar.cpp

_CRT_SECURITYCRITICAL_ATTRIBUTE
void __CRTDECL operator delete(void* const block) noexcept
{
    #ifdef _DEBUG
    _free_dbg(block, _UNKNOWN_BLOCK);
    #else
    free(block);
    #endif
}

Thanks in advance!

Best regards!
