KubePlus chart redeployment encounters failure

On Minikube, if KubePlus helm chart is deleted and then deployed again, it fails to start.
The "crd-hook" container shows the following error:

Trying inClusterConfig..Inside setup
Inside GetExistingResourceCompositions...

panic: Failed to load key pair: open /etc/webhook/certs/cert.pem: no such file or directory
