Kubernetes operator fails to start

[davecodes]

Hi! 
I've tried to follow the quickstart guide for kubernetes and I'm stuck after the first part. I cant get the operator to start successfully. I'm on exoscale managed kubernetes running on v1.25.14. I've downloaded the generated `dynakube.yaml` file and I've executed the suggested script of kubectl commands. My operator keeps failing and restarting with the following log message.

{"error":"Timeout: failed waiting for *v1.Secret Informer to sync","level":"error","logger":"main.controller-runtime.source","msg":"failed to get informer from cache","stacktrace":"github.com/Dynatrace/dynatrace-operator/src/logger.logSink.Error
