First, you need uninstall your workstation.
Then,launch cmd as administrator, go to the folder where the workstation installer package located, and run VMware-workstation-full-15.5.0-14665864.exe -r
Later, a pop-up dialogue will prompt you to reboot the host.
After rebooting, you can install workstation by double click the VMware-workstation-full-15.5.0-14665864.exe .
Could you help a try and update the result here ?
Im not sure if I had installed the update 15.5.1 before
What I did:
download the latest update file
install it and all is fine.
