PHP version	e.g. PHP 7.4.2 (invoke php -v)

Current Behaviour

After update from 0.6.13 to 0.6.14 I get a lot of errors like:

 [ERROR] Could not process                                                      
         "/var/www/module/ProductRelations/src/Implementation/MockRelatedProduct
         sQuery.php" file, due to:                                              
         "Class '_HumbugBoxebb6c51d1e3e\JetBrains\PHPStormStub\PhpStormStubsMap'
         not found".

I use prefixed version.

There's also:

 [ERROR] Could not process                                                      
         "/var/www/module/Przelewy24/src/Domain/Transaction.php" file, due to:  
         "Argument 1 passed to

Looks like first error appear when I have method with iterable as return type:

public function getItems(): iterable {
  return $this->items;
}

We're now waiting for new relase of PHPStan, where it should be fixed
