Hi,
Try to do some actions like mouse move then try to close and reopen vSphere Client.
Check this article: Link

Can you post out the vmware.log from the vm while opening the console and the black console can happen if you happen to have graphics driver with memory set.
Hi, maybe this is not the scenario, but sometimes resolution dns, between vSphere Client and host, will finish in black screen (and a legend with a MKS error),
Regards
There are some more people reporting problems with this. Are you able to go to 5.5?
