The update from macOS Catalina 10.15.4 to 10.15.5 in VMWare Player 15.5.1 worked fine for me. A couple of automatic reboots were required for the update. Tested on 2 systems with 2 different VM’s.

I am using VMWare Workstation Player 15.5.2. I have two Catalina VMs. One worked until I updated the OS from 15.2 to 15.4. The other is 15.2. Neither will go passed the Logo/progress bar screen. The progress bar goes all the way and just hangs. Any suggestions?

The update from macOS Catalina 10.15.3 to 10.15.4 in VMWare Player 15.5.1 worked fine for me. A couple of automatic reboots were required for the update. Tested on 2 systems with 2 different VM’s.
One of the VM’s had a disk space problem when I also tried to update Xcode from 11.3.1 to version 11.4. That was a VM with a virtual HDD of 80 GB. I will have to increase the disk size of that VM. The other one already had a virtual HDD of 120 GB.
