As per the KB the error that you have observed had to be fixed, since this issue is still observed even after patching the host.

VMware Knowledge Base

We would recommend you to create a case with the VMware Support and have them check further.

You could also check the logs for errors reported " /var/log/vmware/vsan-health/vmware-vsan-health-service.log "
