A different custom plugin was messing things up. Deactivated it and now everything working as intended. Thanks!
This is not an answer but I’m having exactly the same problem.

Yoast + Polylang cause indexing issues for the default language.
I have two languages on my site, Global english (en) and US english (en_US) and Google can only crawl and index the US english version which is a secondary language for my site.
One quick fix to the fatal error is to change the line 77 in the same file from
$user_tags = '';
to
$user_tags = array();
