Процесс завершен с кодом выхода при нажатии на вектор вектора указателя C++ ⇐ C++

I'm executing this function to push to a specific location of a vector a new pair of objects. But as soon the program tries to execute the push_back (emplace_back) function. The program gets stuck and I get it returns without any clear errors:

Process finished with exit code -1073741819 (0xC0000005) vector ug; vector foundPaths; void graph::addUndirectedRoute(const city& city1, const city& city2, double distance) { static int maxId = max(city1.id, city2.id); if (maxId >= ug.size()) { while(maxId > ug.size()) { ug.push_back(nullptr); } } if(ug[city1.id] == nullptr) ug[city1.id] = new vector(); if(ug[city2.id] == nullptr) ug[city2.id] = new vector(); ug[city1.id]->emplace_back(city2.id, distance); // execution gets stuck here ug[city2.id]->emplace_back(city1.id, distance); What could potentially go wrong
