@LindyIris10 If you didn't move the mod folder with the mods out, (or didn't disabled the use of mods/scripts in the game's settings), then when you had created a new save, it was still loading the mods, (which would explain why you're having the same error).
1) What mods are you using?
2) Is the game letting you play?
3) If you're able to play, is there any issues you can see? (Such as broken buttons, missing textures, Sims acting in unintended ways, etc.)
4) Have you backed up your saves yet?
The game's save files, (and mods), are stored in your documents folder.
If the documents folder is synced with OneDrive, the file path is:
- "C:\Users\<YOUR-USER>\OneDrive\Other\Electronic Arts\The Sims 4"
("other" is what my OneDrive calls the documents folder).
If the documents folder is not synced with OneDrive, the file path is:
- "C:\Users\<YOUR-USER>\Documents\Electronic Arts\The Sims 4"
(I've tested this file path as well, and it also took me to the same folder location on my PC for The Sims 4)
5) When updating the mods, were you using any mod managers to update them? Were any of the mods manually installed? (As in, did you put them into the mods folder yourself?) If you did manually installed any mods, did you download them from the correct sources? (Third party sites could pose issues and they don't always have the most updated version of the mods).
I'm asking the last question about how the mods are being updated and installed because some mods have multiple components. If any components is outdated, then it would throw an error.
Chances are your mods are mostly updated, but its one or more components that are not. If it is one of these components, then that would explain why no mods are being listed as the issue. It would also explain why it says there's a "broken traits mod" in the report, as it wouldn't be the mod itself, but one of its components. These components would be the mod's packages and scripts. If the mod has multiple packages and/or scripts, make sure every part of the mod is being updated. (This is also why I had suggested CurseForge, as CurseForge would update all the mod's components).
Packages are the items, textures, etc. that the mod provides, while scripts is the extra code used to run them.
For example, a mod that adds furniture, (like the Kitchen mod I have installed), would only have packages as the game has the code for sitting in chairs, eating at tables, etc. If the game didn't have the code for such actions, then the scripts would be included to add them.
6) If you manually added mods, review your mods folder for any mods that may have any outdated components, and update them.
