Upon upgrading to OS Catalina I was warned that some apps MAY not work properly or at all. Listed we a few VMware NOT shown, and the ones that were of little consequence.
I ONLY use the VM to run Win8.? and quicken and turbo tax. They contain a lot of pertinent data. Why the windows rather than Mac version? Up until recently I wanted/needed some of the capability of the windows quicken software. That no longer matters as my needs are not as complex.
So I proceeded only to find the black screen syndrome.
I called apple support to see if I could at least retrieve the pertinent data files. Apparently not. All they could offer was it's a compatibility issue. DOH.
I WAS considering changing over to the on line versions of both of these available for Macs which would have ended my need for Fusion. It now looks like I'm tied, at least to 11.5 to be able to somehow over come the incompatibility issue.
With the host upgraded to Catalina, the Fusion needs to be upgraded to 11.5 or later version to get the support to the new host OS.
If you are using Fusion 11.x, you can upgrade to 11.5 for free.
