Order by count of relational field - php

Question

I have the following relations:
Member one-to-many Product
Product many-to-one Member
This is the query that I have that works:
$qb = $this->createQueryBuilder('m');
$qb
->where('m.Authority = :Authority')
->setParameter('Authority', Authority::CREATOR)
->innerJoin('m.Product', 'p')
->select('COUNT(p) AS HIDDEN item_count', 'm')
->groupBy('m')
->orderBy("item_count", "ASC");
However when I add additional parameters for product status
$qb = $this->createQueryBuilder('m');
$qb
->where('m.Authority = :Authority')
->setParameter('Authority', Authority::CREATOR)
->andWhere('p.Status = :Status')
->setParameter('Status', 1);
->innerJoin('m.Product', 'p')
->select('COUNT(p) AS HIDDEN item_count', 'm', 'p')
->groupBy('p')
->orderBy("item_count", "ASC");
The order by doesn't happen anymore. I dumped the value for item_count and it's alway 1. Has anyone encountered the same problem? The goal here is to get a list of Members with Products with status = 1 ordered by the number of Products.
Edit:
If I change groupBy('p') to groupBy('m'), it will only load one related Product for each Member

For anyone who struggled with the same problem, this is how I did it:
$qb = $this->createQueryBuilder('m');
$qb
->where('m.Authority = :Authority')
->setParameter('Authority', Authority::CREATOR)
->andWhere('p.Status = :Status')
->setParameter('Status', 1);
->select('p, m')
->addSelect('(SELECT COUNT(DISTINCT p1)
FROM Eccube\Entity\Member m1
INNER JOIN Eccube\Entity\Product p1
WHERE m1.Authority = ' . Authority::CREATOR . ' AND p1.Status = 1 AND p1.Creator = m.id
) AS hidden item_count')
->innerJoin('m.Product', 'p')
->groupBy('p')
->orderBy("item_count", "ASC");
It works but I don't understand why this is p1.Creator = m.id ? If I use m1.id it will just sum up the item count.
Edit: Added updated code after Jakumi's comment regarding the join. Even though both code works, the second one makes more sense.
$qb = $this->createQueryBuilder('m');
$qb
->where('m.Authority = :Authority')
->setParameter('Authority', Authority::CREATOR)
->andWhere('p.Status = :Status')
->setParameter('Status', 1);
->select('p, m')
->addSelect('(SELECT COUNT(DISTINCT p1)
FROM Eccube\Entity\Member m1
INNER JOIN m1.Product p1
WHERE m1.Authority = ' . Authority::CREATOR . ' AND p1.Status = 1 AND p1.Creator = m
) AS hidden item_count')
->innerJoin('m.Product', 'p')
->groupBy('p')
->orderBy("item_count", "ASC");
