It's compiling without producing a pdf. Additionally, it has been producing a page with just "chchchch" written on it.

Here's a MWE:

\graphicspath{  {Images/}{../Images/}   }

\usepackage[margin = 1inch]{geometry}                   

\usepackage{amsthm, amsfonts, amsmath,amssymb, siunitx, units, gensymb, array, titling, indentfirst, titlesec, setspace,  upgreek, newcent} 
\usepackage[comma, super, sort&compress]{natbib}

Your are using a wrong argument to the geometry package. It's margin = 1in, not margin = 1inch.

  • Is "inch" allowed for the article document class? Because the document complied fine earlier when it was an article class.

  • inch is not a valid length.

  • I have been struggling with this error for an hour. Wrote "vin" instead of "1in". You're a savior. Commented Mar 17, 2020 at 15:09
