Gitlab installation on Kubernetes v4.6 using operator

Hello
I’m trying to install gitlab on an openshift cluster 4.6 using the operator I tried to follow the documentation and a video on youtube shared by Gitlab channel ( GitLab K8 Operator on OpenShift Container Platform - YouTube ) but I’m facing some issues regarding the installation. after creating the namespace gitlab-system the pod gitlab-controller-manager-xxxxx-xxxx is stuck in ContainerCreating state.

any ideas how to solve that?
TIA
