VSCode Debugging Setting Problem

[BrianHuang813]

I've followed the instructions online to set the environment for compiling and debugging C++ code with using MinGW compiler.
But I've kept facing this error when I try to do debugging. It can successfully compiles the code, but can not do debugging.

And here's my setting in launch.json

Here's my setting in tasks.json

And the last my whole repository

Did I make any mistake in any of the setting ?
