(Small update to make it more clear this is specific to relationship culling, not Sim culling in general).
I was able to procure a save in which this error happened and here's what it looks like without mods in, confirming that at least if the error is somehow related to mods, it sticks into the save once it's there.
Curiously enough, I got the the other relationship error (with Sim IDs that point to nothing) which seems to indicate to me that this error may be fallout from that one.
At the core of it, it's the same issue: when the game performs its routine culling specifically of relationships (through the neighbourhood story "actions" a.k.a. story progression), it calls a function to send telemetry data to EA about the relationships the Sim managed to have before their relationships are cleared out.
Under the cut is the function/the part of the code where the error hits (from performance/performance_commands.py):

This wasn't something that happened before to my knowledge so their code base must have introduced this bug and fixing that will be much harder.
Me too
