same crash a few cycles later

Have you by any chance used the dev debug tools to look at the other asteroids? I've seen this issue primarily when buildings are spawned on other asteroids but are not "active" yet. If that's the case you could try clicking the "Spawn All (Slow)" button in dev debug or spawn a Duplicant on the world with the visible buildings.

However, if that's not the case don't follow those suggestions. If you upload your save I can take a look at what's causing it.

I did recently colonize another asteroid, but there are no POI buildings on it. I'm not sure what to look for using the dev tools. Here's the save, just in case.

I loaded up the save and let it run for a few cycles without experiencing it. Grossola might be causing the problem if anything (only asteroid not visible on the right). Spawning a dupe with the sandbox/debug tools should solve this. Please let us know otherwise.

Changed Status to Known Issue

I misread your player log, the issue has nothing to do with what I mentioned above. It has to do with animating the rockets on the starmap.

Ah, cool, as long as it is a known issue than I'm fine. An occasional crash doesn't bother me. I just wanted to let you guys know since you are doing an awesome job with the DLC.
