How can I remove the ArangoDeployment?

I was able to delete these by patching the metadata.finalizers value:

kubectl -n platform get pod | grep 'agnt\|prmr' | awk '{print $1}' | xargs -ri kubectl -n platform patch pod {} -p '{"metadata":{"finalizers":[]}}' --type=merge

Taken from this post here: kubernetes/kubernetes#60538 (comment)

Removing the finalizers will work, but is not "supposed" to be needed.
What the ArangoDB operator still running when you deleted the deployment?
If possible, it would be great that have the logs of the operator and the output of kubectl get pod, kubectl get service, kubectl get pvc, kubectl get pv

We've seen this problem before but so far we've not been able to determine the circumstances under which is happens.
