Multiple CC/Mod issues

Sooo I played a little, wanted to have a new (base game house) for my Sims, since my build items are gone and my House looks like * now. I placed a house, I could edit it, but I decided I wanted another one. When I wanted to place a new house on another lot, my game crashed and I got another report (see document), I also put the last crash file in there. Does this mean that my game will be fully unplayable? Not trying to be pessimistic, but I lowkey see deleting everything and starting fresh as the only option right now, but I don't want to lose everything I have build up ☹️ 

I hope someone can help me, your help would be so much appreciated!

Hi, I have a really specific problem which I have not seen on the other topics, thats why I am really desperate and starting this new topic 🙂.

I have been playing the Sims 4 with the Sims 4 Folder in Icloud (option that documents and desktop are in Icloud is checked). The game itself with the packs are stored on an external drive. Never had any issues, even with a mods file higher than 60 GB. Until suddenly (well after downloading a little more CC 😉)  my space on Icloud (and also on my Mac itself, though I did not know if this can be the issue since everything is on the cloud?) became smaller. So one time, after downloading some new CC, I got an error (see picture 1). I panicked, starting to update all the mods  (but was too lazy to do it for my cc). This did not work. In Finder, there where lots of icons (picture 2) that I could/should download the files. Never really paid attention to it before the problems, so I was just desperate and right clicked on the Sims Folder (which had that icon) and chose to download the file. THIS TOOK AGES, buttt when it was 'downloaded', the game started. So I thought I had found the solution: everytime I wanted to start playing, I should just download my folder and then it would work. But then my Icloud started to lag, it was almost impossible to download the whole folder, sometimes it would not even start to download, because of the many CC and lack of storage maybe?

First I tried to remove files, photos,... to increase space on both Icloud and mac. Then I took the 2 TB Icloud option (although I have read this won't be helping?). I also tried to uncheck the option for Icloud, so that I could start 'fresh' and resyncing it again, I did see that things downloaded faster. I tried to back up my file, move it to an external drive and started the game again (so it would create a new Sims Folder), then gradually adding files from the back up to the new Sims Folder and testing it multiple times. This was described in https://sims4.crinrict.com/eng/2014/09/resetting-the-game-to-factory-settings-without-reinstalling/. I also made sure to let Icloud process everything before I added something new. Everytime, it worked and al my CC and mods would show up. But then the next problem was my subfolder labeled as 'Builds', where all my build cc items are stored, once I added this one, the game gave the same error, the game would not even start or would start but then shut down again. I have had an Apple report that I tried to decode, but I know nothing off IT so it did not make sense (I added it as a word document 'Trash Report'). I would also get 'Last Crash' files in my Sims Folder (i cannot add more files to this post...). When I try to remove that subfolder 'Builds', it would take away the problem, but sometimes it would keep giving the same error. So I tried repairing the game. Did help, but I desperately want to have CC build items, so this is why I come to this topic, what should I do? 

Then I tried to gradually add some CC to this subfolder, it worked (I only had build items from one creator) but when I started to download other cc build items from another creator, it would give the same error, even if these are newly and thus updated versions of the CC!

Also some background information:

• I had the Curseforge app and downloaded the build items from there (so they would be directly in my Sims Folder), The app also gave a sign that the mods/addons might be corrupt, so I redownloaded them, but this did not help. 
• I play with a Imac 2021 M1, updated to Sonoma 14.5
• I regularly "clean" my mods through the Sims 4 Mod Manager, deleting items I don't use anymore or broken CC, so I do maintain my mods folder
• I also have the Better Exception Mod installed, and the last error it gave was something about "tunable.perf", I saw on Reddit that it has something to do with not updating script mods, but I have done this so where back at nothing... 

I don't want to try with symlinks to have everything on the external drive, especially since it has worked for me to have my Sims folder on the Icloud. Is this a problem with my saves (but it does work after adding them, without the CC installed)? 

Please help, I am sooooo desperate, I don't want to lose everything I have build up. In the mean time I will just play without CC build items, because everything in CAS/Mods work, but I really don't want all the houses I decorated to be gone.

Okay thank you for your help! 🙂

@Pauline241202 Sims 4 Mod Manager is known to cause problems with having multiple mod versions because it renames mods. I strongly advise not using it.

I think that what you really need to do now is to start a fresh Mods folder that no program will rename files in.

1. Delete Sims 4 Mod Manager
2. Rename your Mods folder something like OLD MODS. You'll still have those around to use later.
3. In the Documents > Electronic Arts > The Sims 4 folder, delete all the cache and exception files: https://sims4.crinrict.com/eng/2014/09/delete-cache-files/
4. Start Sims 4. This will generate a new Mods folder.
5. Find that new folder. It will be empty except for a Resource.cfg file dated today.
6. If you want to move that elsewhere with a simlink, do that now.
7. Next, go to your Curseforge app and make sure it's pointed to the new Mods folder.

Next, let's get you some mods installed in that new folder.

Because that mod manager program may well have renamed a lot of your mods causing you to have duplicates, I recommend using your renamed Old Mods folder as a reference for which mods you had but downloading fresh copies. The other reason for that is the tunable.perf error.

That tunable.perf error comes from mods that have a .ts4script file that was updated for the December 5 patch but not reupdated for the February 28 patch. Any .ts4script mod from before December 28 or after February 28 won't have this issue.
