Exception: "unique_object_service failed to handle..."
I last played Sims 4 three years ago and only installed the latest updates in November (did another update just now). Whenever I load my family, there's an exception, with the main error message being:
unique_object_service failed to handle on_all_households_and_sim_infos_loaded due to exception (IndexError: list assignment index (0) out of range)
I already ran a repair and deleted the "avatarcache.package", "localthumbcache.package" and "Resource.cfg" files but none of that fixed it. There are no mods (not even objects or CAS stuff) and I didn't notice any weird behavior, apart from the error.
It doesn't matter if I exit the game completely, exit to the main menu or exit to "manage worlds" before I reload the save, the exception appears every time I load the household and it either creates a new error file (if I restart the game) or attaches the same error message to the already existing file. I already tried to create a new save with "save as", then load it from the main menu but the exception is still thrown.
I've got a couple of old saves and I tested each one: The only one that doesn't cause that error was created pretty much directly after the family had moved into their very first apartment after creating them (a long time ago!). None of the other families are affected but this is the only household I was actively playing and I'd rather not lose it.
None of the saves caused any exceptions when I last played! What's going on here, what's causing the error and how do I fix it?
It won't let me attach the file ("The attachment's lastexception.txt content type (text/plain) does not match its file extension and has been removed"), so here's the full error:
