Simple hello world segfaults in VSCode Run C/C++ file

Question

I am trying to run a simple Hello World program in VSCode, but it is crashing with a segmentation fault. Here is the code:

#include <iostream>

int main() {
  std::cout << "Hello, World!" << std::endl; 
  return 0;
}

When I click Run C/C++ File, I get this output in the Debug Console:

Thread 1 hit Breakpoint 1, 0x00007ff7cf5b145d in main ()
Loaded 'C:\WINDOWS\SYSTEM32\ntdll.dll'. Symbols loaded.
Loaded 'C:\WINDOWS\System32\kernel32.dll'. Symbols loaded.

Thread 1 received signal SIGSEGV, Segmentation fault.
0x00007fff49f3c226 in ?? () from C:\Programs\Git\mingw64\bin\libstdc++-6.dll

I have tried solutions like updating VSCode and C++ extensions, restarting, checking launch config, but nothing has resolved the issue so far.

Can someone please help me understand and fix this segfault when running a simple C++ program in VSCode?

EDIT: It looks like the debugger is trying to load symbols from C:\Programs\Git\mingw64\bin\. I am not sure why the debugger is loading symbols from this path. I have not included it anywhere in the JSON configurations.

EDIT: Actually, this problem occurred when I was working on my OpenGL assignment. A simple cout caused the whole program to crash even before it ran properly. I have tried to include a minimum reproducible example here.

Looks like I finally managed to solve the problem. I renamed C:\Programs\Git\mingw64 to C:\Programs\Git\mingw64ABC, then compiled my program and it ran fine. Then I restored mingw64ABC to its original name and now everything is working correctly as expected. I am not sure whether Windows caches the symbol search paths internally somewhere, that might be the culprit. I am speculating that once the OS had a cache miss, it removed that path from the list and appended the correct search path C:/msys64/mingw64/bin/.
