LaTeX hyphenation and line breaking not working

I am unable to produce a simple text with hyphenated words and justified lines with PDFLatex.

Here is a MWE

documentclass[12pt,openright,a4paper,twoside]{article}
%usepackage[utf8]{inputenc} %It does not change anything
usepackage[english]{babel}
usepackage{kantlipsum}
usepackage{indentfirst}
%usepackage{hyphenat} %It does not change anything

begin{document}

    kant[1]
    
    discontinuous discontinuous discontinuous discontinuous discontinuous discontinuous discontinuous discontinuous discontinuous discontinuous discontinuous discontinuous discontinuous discontinuous discontinuous 
            
end{document}

here is the output

here is the log file
