EKS csi secret store driver not finding SecretProviderClass

I'm trying to use parameter store and secret manager in my EKS cluster but i keep getting this error:

MountVolume.SetUp failed for volume "secrets-store-inline" : rpc error: code = Unknown desc = failed to get secretproviderclass fastcode/helloworld-secrets, error: SecretProviderClass.secrets-store.csi.x-k8s.io "helloworld-secrets" not found

and inside secret store provider logs:

secretproviderclasspodstatus_controller.go:99] "failed to patch secret owner ref" err="failed to get spc helloworld-secrets, err: SecretProviderClass.secrets-store.csi.x-k8s.io "helloworld-secrets" not found"

Both pod and SecretProviderClass are created with helm. SecretProviderClass and pods are in the same namespace

apiVersion: secrets-store.csi.x-k8s.io/v1
kind: SecretProviderClass
metadata:
  name: helloworld-secrets
spec:
  provider: aws
  parameters:
    objects: |
        - objectName: "/password/db"
          objectType: "ssmparameter"
          objectAlias: "dbpassword"
        - objectName: "/password/instance"
          objectType: "ssmparameter"
          objectAlias: "dbinstancepassword"

volumes:
      - name: secrets-store-inline
        csi:
          driver: secrets-store.csi.k8s.io
          readOnly: true
          volumeAttributes:
            secretProviderClass: "helloworld-secrets"

What should i do?

Thanks
