@muglug , it seems the problem still occurs in the class.

I found these snippets:

<?php
  
class A
{
/**
 * @template T of object
 * @psalm-param array<T> $collection
 * @psalm-param callable(T, T): int $sorter
 * @psalm-return array<T>
 */
public function order(array $collection, callable $sorter): array
{
  usort($collection, $sorter);

  return $collection;
}
}

Psalm output (using commit 508c2e2):

ERROR: InvalidScalarArgument - 13:22 - Argument 2 of usort expects callable(object, object):int, callable(T:fn-a::order as object, T:fn-a::order as object):int provided
