How to reproduce
Absolutely No idea! I'm doing >100k scans and this issue has only popped up less than ten times. Sadly, I did Not capture what domain, what TLD this error occurred on. All I can say, is that it was a ccTLD

Possible Solution
How to fix the root issue? No idea! How to potentially slap a bandaid on it? (untested) && is_string($str) in if ($str && is_string($str) && preg_match($fallbackRegex, $str)) { (BlockParser.php:430)

Additional context
N/a
