The expression preg_replace('/<(\\/?(?:title|textarea|style|xmp|iframe|noembed|noframes|script|plaintext)[ \\/>])/i', '&lt;$1', $rendered); of type string|string[] adds the type string[] to the return on line 41 which is incompatible with the return type declared by the interface League\CommonMark\Inline\Renderer\InlineRendererInterface::render of type League\CommonMark\HtmlElement|string|null.
