Sim won't accept queued commands

I found her in another area of the house and noticed she had queued herself up to take a bath in the tub upstairs, which seems to be her favorite. But she just stood there until it dropped. I tried to make her take a bath in the tub you see her standing in front of and that failed. And then I tried to get her to go sit on the couch just outside that bathroom and that failed as well. 

I do not use mods or cc.

I updated my game yesterday, but didn’t actually play it as I do use mods: UI Cheats, MCCC, and Wonderful Whims and I wanted to wait for them all to be updated. Other than that, I have a lot of CAS custom content. I decided to start a new save and wanted my Sim to read a book. I queued it up, but my Sim was just standing outside. I reset her and clicked on a random spot on the floor for the “go here” command, and she did that. Still wouldn’t read the book when I clicked it. I used the go here command again to get her upstairs and in front of the bookcase. Still wouldn’t read the book. Wouldn’t sit on her bed. Would do anything. I’m going to try taking out my mods folder next, but other people that don’t use mods are having the same problem, so I don’t have much hope tbh

Update: About 15 minutes later, no mods (as show by my oddly pale and bald Sim 😂), the game is just literally not working. Everyone stood around doing literally nothing, not even talking. She still wouldn’t do anything I queued up. This game is simply hopeless

I started a new save yesterday after updating the game and my mods and moved the sim to Nordhaven. I wanted her to go inside and read a book, but she wouldn’t move. The queued action didn’t move either. I reset my sim and she still didn’t move. I tried the go here command and she walked into the house no problem. I queued up the book again and still nothing. I used the go here command again to walk her upstairs to the bookshelf and she still didn’t take the book to read. My sim also didn’t sit down when I selected a chair or her bed, either.

I closed the game and removed my mod folder since I thought maybe Wonderful Whims might have been messing something up since that’s the one mod I use that wasn’t updated. I loaded the game up again and selected an old save, shown below with my sim without her custom skin or hair. I told my sim to sit down, but neither she or the other two Sims moved to do anything at all for the five minutes I left the game running without doing anything. They didn’t sit, they didn’t walk around, they didn’t judge the furniture, they didn’t even talk. They just stood there occasionally looking around.

This particular issue already has one (or several) threads but I didn't have the time to go look for it so it's locked for upvotes.

Since the latest update, Sims have been getting stuck when I give them a command. I have been trying to complete the challenge and they will just do the idle animate when I tell them to watch TV, talk to stuffed animal, etc. Resetting the Sim through shift + click does clear the queue but they freeze again when I retry the action. I usually play with a few mods (no CC) on a large save file so originally thought the problem was just lag, but even after a clean install + new save file it is still happening! It's not every single command (they will still obey 'Go here' and a few others) but still super disruptive and means I haven't been able to do the challenge :(
