Open vendor/magento/module-catalog/Plugin/Block/Topmenu.php
The constructor of this class looks like
public function __construct(
\Magento\Catalog\Helper\Category $catalogCategory,
\Magento\Catalog\Model\ResourceModel\Category\StateDependentCollectionFactory $categoryCollectionFactory,
\Magento\Store\Model\StoreManagerInterface $storeManager,
\Magento\Catalog\Model\Layer\Resolver $layerResolver
)
Now, open TemplateMonster\Megamenu\Plugin\Block\Topmenu and take a look at its __construct method.
Your first check should be if parent::_construct() is called.
If it does, what parameters are send there?
Your checks here:
A. Does parent::__construct receives 4 parameters?
B. What variable is send as a second parameter?
This last one is actually the problem: the second parameter that you send is NOT of type
\Magento\Catalog\Model\ResourceModel\Category\StateDependentCollectionFactory
but of type
\Magento\Catalog\Model\ResourceModel\Category\CollectionFactory
Inject the correct type for the second parameter, confirm that the rest are send as expected, re-compile if you must, and you are done :).
I hope this helps.
Please re-check your code.
Try to find classes constructor with
\Eav\Model\Entity\Attribute\Source\ConfigFactory
in code you have line like this
$this->configFactory->create();
but should be
$this->configFactory->create($optionsData);
You should pass parameter into factory create function.
I hope it will help you to solve this issue.
