That looks pretty ominous actually, illegal instruction is a bad one! Essentially I think you either have a corrupted install, or your Rosetta version is not coping with this game.
What I'd suggest is a full clean reinstall of the game:
- move any valued save games elsewhere; they are under
~/Library/Application Support/Surviving Mars/{large number}/
- "uninstall" in Steam-Surviving Mars
- manually delete both the ~/Library/Application Support/Steam/SteamApps/common/Surviving Mars AND ~/Library/Application Support/Surviving Mars/ folders
- re-install game in Steam, run a Steam Verify when done.
- start the game with no mods active and test
In particular you need to make sure there are no files or folders left under either the Steam SM or Application Support SM locations, before installing again.
IF that doesn't help can you update to MacOS 12.2.1 , to get the latest Rosetta version?
