Just an FYI for anyone: I deployed an 8.5 appliance a few months ago and had the same issue. I had to upgrade to 8.6.2 at the direction of management (log4j) and am still having the same issue. I've rebooted, cleared cache, etc, but nothing changes. It doesn't matter what object I view, VM, datastore, host, vSAN, vCenter, they all have blank pages showing fields populated with no data. I try Metrics and nothing shows up besides the panes for selecting the metrics.
This is only on Chrome, which is up to date. I flipped over to Edge and Firefox and they work just fine. I hope this helps anyone.
