[FIXED] Merging households through dialog doesn't proceed

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.103.315.1020
What expansions, game packs, and stuff packs do you have installed? For Rent, Growing Together, High School Years, Seasons, Cats and Dogs, City Living, Get to Work, Parenthood, Home Chef Hustle, Nifty Knitting, Tiny Living, My First Pet Stuff, Laundry Day, Movie Hangout, Book Nook Kit, Bathroom Clutter Kit, Everyday Clutter Kit, Little Campers Kit.
Steps: How can we find the bug ourselves? You can ask someone to join your household.
What happens when the bug occurs? When the screen "Split from household and move" appears, it kind of freezes. I cannot cancel the action and I cannot make the new sim join MY household. The only option that is allowed is my sims have to move out of their house to join the new sim household. In the example attached, Tanaka is my family. I asked Lê to join my household, by only my family Tanaka can join Lê's household. Not only that, when I select the only option available, I have to sell all the furniture in my house! I just lost a huge part of my gameplay because I had to close the game, since it wouldn't allow me to do anything else besides join the wrong household!
What do you expect to see? I'm expecting to have the new sim joining MY household with no problems!
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure

It's not the first time this issue has happened to me. Every time I ask someone to join my household it happens. I've done it in different saves and I had the same issue.
