<?php
    public static function getInstance(): self
    {
        if (self::$instance === null) {
            self::$instance = new self();
        }

        return self::$instance;

The expression return self::instance could return the type null which is incompatible with the type-hinted return Smoren\PartialIntersection\Util\NoValueMonad. Consider adding an additional type-check to rule them out.
