I actually had and resolved this error within the last couple of days. There is some discussion here:

Topic:Ukv6pdo96a8qfur2

In the end, what resolved it for me was installing composer, php-mbstring and php-xmlwriter, then running this command in the extensions/TemplateStyles directory:

composer install --no-dev

 Done Problem solved when I updated my wikimedia/css-sanitizer into 2.0.1.
