From the screenshots, it looks you are using ESXi host client version 1.25.
Try updating to the latest (currently version 1.29), it might be a problem that is resolved in subsequent releases.
I did this
esxcli software vib update -v http://download3.vmware.com/software/vmw-tools/esxui/esxui-signed-8122819.vib
the installation was successful, I restarted the ESXi, but the problem remains. And now, I don't even have the option to view the details of the error.
The original error
Cause: TypeError: Cannot read property 'vbsSupported' of undefined
If I were to have a guess, it possibly related to support of the Virtualization Base Security (VBS) feature which is available on virtual hardware version 14.
It would seem that the ESXi host client failed to find that property in the VM.
I looked at the required answers shared, however can you advice if we tried connecting on a different Browser, may be Firefox.
I faced the same issue and after updating the vib i tried connecting on Firefox which fixed the issue.
From the below link, we can see on the bugs tab that many 'Cannot read property....' issues were fixed in the recent version of the client. bluefirestorm hunch was bang on!
