Gitlab Backup Restore Error

Hey,
i want to restore a GitLab Backup which I have from my old Kubernetes Cluster into the new Cluster, I read this Howto inside the Docs (Restoring a GitLab installation | GitLab) the Backup restores without any errors. At the point who says " Enable Kubernetes related settings" and I run the following command: (kubectl exec -it – gitlab-rails runner -e production /scripts/custom-instance-setup) it throws me an Error:

kubectl -n gitlab-system exec contentways-gitlab-toolbox-95984bd4d-s4ptc -it -- gitlab-rails runner -e production /scripts/custom-instance-setup
Defaulted container "toolbox" out of: toolbox, certificates (init), configure (init)
Disabling authorized keys write in the database.

When I restart the Pods they didn’t come up and get stuck at Init:CrashLoopBackOff, what is going wrong?
