C++ Uniform initialization doesn't work with "expected ';' at end of declaration"

Question

I'm the beginner of C++. I set development environment in vscode in Mac. But I trapped in variable initialization. Copy initialization and direct initialization are ok, but uniform initialization doesn't work.

#include <iostream>

int main() {

    int a(0);

    int b = 0;

    int c{0};
    
    int d = {0};

    int e;

    std::cout << "Hello World";

    return 0;
}

In this code, int c{0}; doesn't work. It failed to build. It printed error: expected ';' at end of declaration

What can I try to solve this problem??

I don't know if it helps, but I'll upload ".vscode".
