Velero- Restore partially fails for a specific namespace

[MLeonidou]

Hello everyone, soo i am encountering the following issue, I want to backup and restore a specific namespace (demo) which i have on an openshift cluster. The backup is completed successfully but when i am trying to restore it is Partially failing everytime. I my last attempt i the status changed to Completed but containers could not be properly built cause are unable to pull or push the image.

I have read that at least in restoration procedure system resources like CSV etc should be excluded
https://docs.openshift.com/container-platform/4.9/backup_and_restore/application_backup_and_restore/troubleshooting.html

Here is the command i have been trying over and modified it multiple times against the warnings and errors I was getting

velero restore create --from-backup demo
--exclude-resources=configmaps/kube-root-ca.crt,configmaps/openshift-service-ca.crt,builds,rolebindings,clusterserviceversions.operators.coreos.com,imagetags.image.openshift.io

The errors and warnings i am currently getting:

Warnings: Velero: Cluster: could not restore, CustomResourceDefinition "clusterserviceversions.operators.coreos.com" already exists. Warning: the in-cluster version is different than the backed-up version. Namespaces:
demo: could not restore, ConfigMap "kube-root-ca.crt" already exists. Warning: the in-cluster version is different than the backed-up version.
