Unable to debug on wsl ubuntu any C++ project using remote VSCode gdb

Brief Issue Summary

Unable to debug on wsl ubuntu any c++ project using remote VSCode gdb

I try to debug perfectly OK executables, which I can manually debug with gdb, but trying to debug on VSCode gives the error attached below, in which every executable return right away with exit code 42.
Couldn't find anything online about this.
The problem reproduces on my machine with the following simple project:

Main.cpp

#include <iostream>

int main()
{
	std::cout << "insert x:\n";
	int x;
	std::cin >>x;
	std::cout << "hello x="<< x<< "\n";
}

ERROR: Unable to start debugging. GDB exited unexpectedly.
1: (610) Send Event AD7ProgramDestroyEvent
The program '/home/theroyn/repos/hihi/build/server' has exited with code 42 (0x0000002a).

Reproduce the failure with Main.cpp, CMakeLists.txt, and .vscode/launch.json under WSL Ubuntu, comparing manual gdb with the VS Code launch. Start with the provided debug log around the shell and debugger exit, then trace the relevant launch path. Done means the sample executable starts debugging through VS Code without exiting unexpectedly.
