Cubase Pro 13 Dolby Atmos Renderer Bug

Hello, thank you for taking the time to read.
I am new to Atmos and I’m attempting to learn how it works in Cubase, with binaural headphone rendering for now.
I’ve done all of the research I can over the last several days to understand what Atmos is, and what the possibilities and limitations are. It’s pretty exciting to me.

Things were going well at first, making progress slowly by messing around with things until I figured them out. At first I was trying to keep my stereo compressor plugins in the project by using stereo group tracks that I then routed to beds.
Then, I got rid of the stereo groups and went all in on beds with a few objects like kick, snare, and vocals.
Finally, I’ve arrived at the ideal workflow for me - all objects. It seems that this method gives me the most options, and better binaural translation.

Well, like I said, things were going well, until I saved my first object-only project and closed Cubase. When I came back to it later and opened the project, I was met with an error dialog saying:
“Object IDs could not be assigned. Check your settings in the Audio Connections dialog and the External Dolby Atmos Renderer Setup dialog.
You can either accept unassigned object IDs or automatically assign new object IDs.”
I clicked the option to automatically assign new ones.
But now, when attempting to play back the project, I hear nothing. Only when I remove the renderer plugin from the output do I hear audio.
I searched these forums and some people said to make an Atmos template, load that, activate it, and then open your original project back up to get the renderer to work. That isn’t working for me.

FWIW, I have also attempted to open the project in Cubase Pro 14 (I started a 60-day demo of that version today in order to test this.) I got the same error dialog about Object IDs, and the same bug with the renderer.

As a last ditch effort, I transferred the project to my Windows machine and opened it in Cubase Pro 14 there. Same error, same bug. No plugins active in the project as it’s a fresh install of Cubase on a machine that wasn’t being used for audio production.

Okay, I found a solution. I created a new project, used the Setup Assistant, and then used Cubase’s “Import Tracks From Project” feature to get all of my tracks from the other project back. I then used the Create Objects From Selected Tracks feature in the authoring panel to reconnect everything to the renderer.
I did quickly test to see what happens when I closed Cubase and reopened the project. It opened fine with no errors and the renderer is playing back.
