You probably have some old CRD that is causing the issue. Try to remove the operator, show all CRDs in the cluster and look for Dynatrace OneAgent CRDs. Just delete these CRDs and reinstall OneAgent operator. In my case, I had to delete these two: oneagents.dynatrace.com and oneagentapms.dynatrace.com

as Leonardo Cardoso mentioned, delete old CRD

kubectl delete crd oneagentapms.dynatrace.com
kubectl delete crd oneagents.dynatrace.com
