Bug Summary and Steps to Reproduce

Bug Summary: I am trying to learn C language with openclassroom. Downloaded WSL and Ubuntu, then C/C++ extension for visual code and followed every step. Created my first directory ('projects' then 'myfirstproject') and first files ('helloworld.c' and 'variables.c') without any problems. I can run them in VC without any issue.

Now i've tried to created a new directory and new files. Everytime I try to run the files in visual code it tells me : the prelaunchtask c/c++: gcc build active file terminated with exit code -1. Then when I try to debug it it tells me : launch: program '/home/my_username/projects/myfirstprogram/main' does not exist.

I've read everything I could find about this error. I've tried to add my GCC to "PATH", I've relaunched my computer, I've tried uninstalling ubuntu and wsl and reinstalling them... Now i can't even find the files and directory in wsl.localhost anymore. I'm a beginner when it comes to all of this and I'm honestly at a loss for what to do...

The code I'm trying to reproduce is in the first video of this page : https://openclassrooms.com/fr/courses/19980-apprenez-a-programmer-en-c/7528516-initiez-vous-a-la-programmation-modulaire.

I hope you'll be able to help me, thank you!!
