@LindyIris10 First off, the first image says there's a bad tuning in the mod "Realistic Teens", but then it says to check the broken mods section, to which the mod "WhoIsKnocking" is marked as an invalid script.
Basically, "Realistic Teens" seems to have just errored out because you had generated the Better Exceptions report. The issue lies with the "WhoIsKnocking" script.
You need to move the script directly into the mods folder, meaning:
The Sims 4 \ Mods \ <Here>
You currently have it:
The Sims 4 \ Mods \ Another Folder \ <Here>
Lastly, the "Patch Day Results", this is typically an overview of mods that are outdated. It doesn't mean that they're broken, but it could be what's causing issues.
The example it gives explains it best:
"Let's say you filled out a form asking for your first and last name. Later we updated it to require your birth date. When we ask for your name, it will work, but when we ask for your birth date, it wouldn't work."
In other words, the mods listed, (such as "Khals Carryup Animation Interaction"), were made for a previous game version. They'll still "work", but certain parts of it can cause issues.
Recommended:
1) Remove "Realistic Teens" or update the mod.
2) Moving the "WhoIsKnocking" script file directly into the mod's folder. (It cannot be in a folder within the mod's folder, it must be directly after the mod's folder).
3) Launch the game and see if the error is still there.
4) If the error still occurs, check all the mods that were flagged in the "Patch Day Results" for any updates.
5) If any of the mods listed in the "Patch Day Results" don't have any updates, you should remove those mods. (You could also wait for an update to these mods, but keep in mind that developing mods do take time and the developers of these mods may be very busy).
These mods are only recommended as a starting point by Better Exceptions, because they could very well still be working, its just that they weren't developed for the current version of the game. It is possible that some or none of these mods would need to be removed, its just a "better safe than sorry" type of thing.
Considering other households work just fine, its most likely just a bug that occured in the broken household when you had loaded it up on the latest version prior to updating any mods. These things tend to happen, and that's also why the game will warn you after each update and would disable mods and their scripts automatically.
