Could you update to 11.5 to see if you still hit this issue?
I got same problem with the previous version... this event makes me think...
If you are running on macOS Catalina then AFAIK the only way to fix this is to update to VMware Fusion 11.5.
If you are not running macOS Catalina then you might have another issue that the vmrest service isn't able to communicate to your localhost.
This might be due to a firewalling issue or something else like a broken installation.
