Symfony 5.4 trouble setting up drenso/symfony-oidc-bundle - symfony

Question

Im trying to set up an open id connection with this bundle https://github.com/Drenso/symfony-oidc. Did the first step of configuration
drenso_oidc:
#default_client: default # The default client, will be aliased to OidcClientInterface
clients:
default: # The client name, each client will be aliased to its name (for example, $defaultOidcClient)
# Required OIDC client configuration
well_known_url: '%env(OIDC_WELL_KNOWN_URL)%'
client_id: '%env(OIDC_CLIENT_ID)%'
client_secret: '%env(OIDC_CLIENT_SECRET)%'
# Extra configuration options
#redirect_route: '/login_check'
#custom_client_headers: []
# Add any extra client
#link: # Will be accessible using $linkOidcClient
#well_known_url: '%env(LINK_WELL_KNOWN_URL)%'
#client_id: '%env(LINK_CLIENT_ID)%'
#client_secret: '%env(LINK_CLIENT_SECRET)%'
Variables are also set in my .env.
when i enable oidc in my security.yml, this happen :
here's my security.yml :
security:
enable_authenticator_manager: true

App\Entity\BackUser: auto
App\Entity\FrontUser: auto

chain:

# success_handler: App\Security\Handler\LoginSuccessHandler
logout:

target: front_index
handlers:
- App\Security\Handler\LogoutHandler
I just cant figure out why this happen. If someone has a clue or has already used this package and may know what i'm doing wrong?
wishing y'all a good day
