No operator >> matches these operands ifstream

I am coding in Visual Studio Code, using C++. I am getting the following error, "no operator >> matches these operands". Can you please tell me what I am doing wrong? (The error is occurring on the line, fin >> N.)

#include <fstream>

int solve() {
    std::ifstream fin;
    fin.open("race3.in");
    int N;
    fin>>N;

    std::ofstream fout;
    fout.open("race3.out");

    fout.close();
    fin.close();
}
