Stuck on loading after hitting save

Okay so I just started a new save and saving did work there. After that I tested my main save and it didn't work there so I still don't know what the problem is.

@PineAppleLot8  Can you use "save as" rather than "save"?  Please try it and let me know.  If that doesn't work either, switch to a different household and use "save as" there.  You'll be creating a new save rather than overwriting your current one, so don't worry about lost progress.

Please test with no mods or custom content, at least for now.

Okay so I just spend almost 1,5 hours trying multiple things. "Save as" did nothing. I tried multiple saves and multiple households. There was a whole other save that had no problems and an other save that wouldn't even load the household (both had only one household that I made and played with). Then I made a copy of my main save file and started it without my mods. No change. I removed all my cc as well and that helped in the different version of my main save file. I started placing folders back and restarted the game and tried again trying to find what was wrong. I placed everything back but the cc category and it still worked. Then I opened another version and somehow it didn't work in that one. I also tried that other save where I couldn't open that household and that was also not fixed. 

So I think there is something wrong in my cc files? Is there a way to know what exactly is causing the problem?

My main save file works normally without mods and cc. I think the problem is caused by something in the cc folders, my mods aren't the problem, that I do know. 

So it's something in my skin details folder (skin blends, tattoos, eyecolor defaults, nails etc.) The game works fine without that folder

@PineAppleLot8 If you narrow it to something not already listed in newly broken or previously broken in Broken/Updated Mods & CC , please let me know.
