Problem with the first C++ code and installation of MinGW-w64 toolchain

I was trying to learn C++ programming using VS Code, but I ran into the following problem. When I launched the program from the official VS Code website, I got the error shown in the screenshot. Exit code: -1. What does it mean? How can I fix it? There aren't any errors in the code itself, but something's wrong with the compiler. I was confused by the errors shown in the other screenshot that appeared in the terminal during the installation of the MinGW-w64 toolchain. I searched online for information about this, but I couldn't seem to find the solution I needed. So, how do I fix all this?

MSYS2 errors
