My iMac Pro is running the latest version of Mojave. After buying the upgrade for Fusion 11.5 yesterday I installed it on the iMac, which has not had Fusion or any other VM software on it before. I then created a new VM for Windows 10 64b, and installed Windows 10 Pro 1909 using a freshly created Media Creator Tool USB flash drive. The install went fine and I was able to activate it and repeatedly use it to install additional Windows updates. Everything seemed fine.
But after a couple of instances where I could not paste text from the Mac clipboard into Windows, even though clipboard sharing was enabled in Fusion settings, I realized I had not installed Vmware Tools yet. I found that option in one of Fusion's drop-down menus and completed the Tools installation. Upon completion the VM was much higher resolution. I restarted it and it took me to the Windows login screen. After entering my PIN number the Fusion window turned black and did not change. I finally used the Option key to Power Off the VM, whereupon I rebooted, logged in and got the same black screen. There are many videos and references to similar sounding problems with Fusion but usually Catalina is involved. I'm using Mojave. Any suggestions?
