Confirmed, and solved. There is a problem with the MikTeX xstring
package -- its missing xstring.tex. So, (i) download xstring.zip from
CTAN, (ii) pull out the xstring.tex file, (iii) copy it into the xstring
folder in miktexz/tex/latex/xstring, and then (iv) rebuild the DB.

Tried applying latest updates, and several files which compiled

working with, but which - apparently - is called by something else.
Before the update, the installed version was "1.7c / Wed Oct 23 2013".
The latest "source" shown in the update application is "1.81 / Tue Dec
2018". If I apply the update, and try a compile I get the following error:

! I can't find file `xstring.tex'.
l.1 \input xstring.tex
Please type another input file name:
So, apparently, it can't "find" xstring.tex"
which doesn't surprise me, since there is no xstring.tex file, but
there is an xstring.sty file (the first line of which is
\input xstring.tex
I'm guessing this is a resurfacing of a bug reported here:
