Cannot autowire service "splash.akeneo.security"

[docteurmabuse]

Hello,
I've got this error on cache flush:
Cannot autowire service "splash.akeneo.security": argument "$provider" of method "Splash\Akeneo\Services\SecurityService::__construct()" has type "Splash\Akeneo\Services\UserProvider" but this class was not found.

Thanks for your help.

Thanks.
