This exact same thing happened to me too. Tried merging households through dialogue, but that window freezed. Then I tried to merge households via manage worlds, tried to load into the household and then I got the errorcode: 102:33015dcc:99c26b61
Also; I'tried to merge Dina Caliente into the Catarina Lynx household in Brindleton Bay when this errorcode occured.

Did this issue appear after a specific patch or change you made to your system? Yes
Please describe the patch or change you made. I don't merge households that often so I can't say . I've installed the most recent patch from September 18th and I just installed home chef hustle, but I think that last thing should be irrelevant.
