OOP Vector edit issue - c++

Question

I have created a function that should edit the attributes of a class stored in a database. However, the vector insert function doesn't work as I expected. Could someone please suggest how I should implement the insert vector function to fill the hole I have made?
Whenever I implement it, this pops up:
Process finished with exit code -1073741819 (0xC0000005)
Code:
using namespace std;
int Natobase::counter = 0;
Natobase::Natobase(string n, string ci, string co, int ri, int tan, int pla, int lan)
: name(n), city(ci), country(co), rifles(ri), tanks(tan), planes(pla), launcher(lan) {};
Natobase::Natobase(string init) : Natobase("20thDiv", "Kuldiga", "Latvia", 100, 50, 75, 32) {};
std::ostream &printnames(std::ostream &pr, Natobase &pro) {
pr << "\nID:" << pro.ID << "\nName:" << pro.name;
return pr;
}
std::istream &operator>>(std::istream &re, Natobase &product) {
std::cout << "Enter the name of the base: \n";
re >> product.name;
std::cout << "Enter the city where it is located: \n";
re >> product.city;
std::cout << "Enter the country where it is located: \n";
re >> product.country;
std::cout << "Enter the number of guns held: \n";
re >> product.rifles;
std::cout << "Enter the number of tanks stationing: \n";
re >> product.tanks;
std::cout << "Enter the number of planes stationing: \n";
re >> product.planes;
std::cout << "Enter the number of launchers stationing: \n";
re >> product.launcher;
product.get_counter();
product.ID = product.counter;
return re;
}
**void Database::EditDB() {
Natobase nato;
int editt;
cout << "Enter the number of the base that you want to change:\n";
std::cout << "The bases are:\n";
printids();
cin >> editt;
auto iter = std::find_if(std::begin(DbMain), std::end(DbMain), [&](Natobase& nb)
{ return nb.get_ID() == editt; });
if (iter != DbMain.end())
{
DbMain.erase(iter);
cout << "\nPlease enter the input of the base one more time" << endl;
cin >> nato;
DbMain.insert(DbMain.begin() + iter->get_ID(), nato);
cout << "\nSuccess";
}

From this erase reference:
Invalidates iterators and references at or after the point of the erase, including the end() iterator.
After you called erase the iterator iter is no longer valid, it can't be used anymore.
If you need to use data from it you need to copy it first before you call erase.
You also need to use the iterator that erasereturns if you want to continue your loop.
