For those encountering this error on “Your First Program” for " C++ Fundamentals: Game Programming For Beginners", don’t worry, there’s an easy fix 
I created a GitHub repo with a new template that should work:
BE SURE TO FOLLOW THE README INSTRUCTIONS ON GITHUB!
You will need to install Raylib version 3.7 as shown in the videos and I included a link to download it for Windows as well as a link to other versions if needed.
The reason this is happening is that the .json files in the template downloaded from Gitlab are referring to a folder structure that seems to have been changed by Raylib.
So, my template has updated .json files.
For example. around line 16 of “c_cpp_properties.json”, you should notice an attribute called “compilerPath” with “C:/raylib/w64devkit/bin/gcc.exe” written next to it.
This would need to be changed from “C:/raylib/w64devkit/bin/gcc.exe” to “C:\raylib\mingw\bin”.
There are however many more lines where similar fixes will need to be implemented, so to save time you’re welcome to use my template instead
If you do fix it yourself, you will need to reload the workspace for the changes to take effect.
So be sure to save your changes, then close VS code, and open the workspace again from scratch as shown in the video.
I hope this helps.
But I’ll be happy to help with questions or concerns if there are any
