Hi everyone,

I'm facing an issue with the Spryker Merchant Portal. When I try to open the portal, I encounter the following error:

Interface

"Symfony\Component\Security\Core\Authentication\Provider\AuthenticationProviderInterface"

not found

I am getting this error after upgrading my code while opening merchant portal.
