[OS X TeX] "can't use \end in internal vertical mode"

Wed Aug 8 16:32:02 CEST 2018

This query replaces a flawed one I sent a few minutes ago.

I am confused by the following error.

I copied the format of the attached tex file from a previous tex file which compiled successfully in the past.
But when I try to compile it, I get the error message in the subject line above.
Here is the tex file I am trying to compile (text to be added later)

And here is the output on the console when I try to compile:

This is pdfTeX, Version 3.14159265-2.6-1.40.18 (TeX Live 2017) (preloaded format=pdflatex)
 restricted \write18 enabled.
