Operator pod in CrashLoop state

Trying to install the latest operator from OperatorHub, but the operator pod kept restarting after the following message is showed:
```
{"level":"error","ts":1636148065.0665808,"logger":"setup","msg":"problem running manager","error":"open /tmp/k8s-webhook-server/serving-certs/tls.crt: no such file or directory","stacktrace":"github.com/go-logr/zapr.(*zapLogger).Error\n\texternal/com_github_go_logr_zapr/zapr.go:132\nsigs.k8s.io/controller-runtime/pkg/log.(*DelegatingLogger).Error\n\texternal/io_k8s_sigs_controller_runtime/pkg/log/deleg.go:144\nmain.main\n\tcmd/cockroach-operator/main.go:122\nruntime.main\n\tGOROOT/src/runtime/proc.go:225"}
```
Operator version: v2.3.0
Kubernetes: Openshift 4.6.21

Any help will be appreciated!
