Stdlib.h Missing?

I have run into this issue with Coding studio where any file I try to download to the brain, it will kick out an error: (Coding studio was working yesterday)

Error: ‘stdlib.h’ file not found

What I’m running:
Windows 10 Home, Build 17134.
HP 24-b217c.
x64 Based.

I have Tried:

  • Windows Fresh Start.
    *Uninstalling, Deleting respective appdata folder, restarting, and reinstalling
  • Copying Code to new file

What has temporarily worked: (Meaning it worked for about a week)
Windows Fresh Start.

The file is there. I didnt put it there. Coding studio did. Still Doesn’t work

what I would do is copy/paste the code into a new file but keep the old one just in case something happens. I don’t know what else to do.
