Thanks for the reply. I'm on Windows 10 1903. My Mac VM was working fine on Vmware 15.0.2. When I went to update to Windows 10 1903, Windows actually required me to update Vmware to 15.1, saying that 15.0 was incompatible with it. So then I updated to Vmware 15.1, and then was able to install Windows 10 1903. The VM had been fully shutdown before either of these updates. Now, when I try to boot the Mac VM up, it shows the apple logo, with a progress bar that takes a while to get to the halfway mark or so, and then reboots itself and does until I power it down.
I have tried deleting the .nvram file (which has worked before) but that didn't fix anything. I have also tried unisntalling the unlocker and then putting it back, several times. Neither of these worked.
Please let me know if you have any ideas.
