Error code 123: 259a6556: 5e24aec7

I cant even test which mods dont work cause none of my mods will show up in the game! 

MarahCricut​ You'll find lots of good resource lists and how-to's linked for you in Mod & CC Issues: START HERE 

ok it worked so that means a mod might be the issue.

unfortunately, it's now at the point now where i click on anything in the sims 4 gallery it says the item is corrupted and it shows a red X with loading symbol any idea what that is too? And no I can't even play the sims 4 live mode when I have my mods disabled.

MarahCricut​ How did you check? If you didn't rename or remove your Mods folder and delete your localthumbcache file, you haven't finished checking. 

That said, mod removal can also cause this. Can you load other households with your current mods? If you remove all mods/CC and move your Sims to a new house, can you load it? 

See vanilla and 50-50 testing

ok now I won't stop getting the 102 error and i checked all my mods and nothing is wrong with them!

So, I create a household to play, and I do everything correctly but then it says gameplay error so I can't play live mode I can only build and manage worlds and I don't get stuff o loading either I just can't do live mode.

I cannot play my sims 4. When i try to load a new game or already played game it sas it cannot load succesfully. I tried to download it with steam but that didnt help. Now all my expansion packs has deleted from my computer and i canoot download them again cause it says that its already downloded. So now my sims doesnt work at allt and its really irritating since I really like this game and enjoys it very much

Thank you so much.

kaykay_cxx​ Just going to add that if you have that AstroBluu mod, you could well have other broken ones. Start at Previously Broken mods and CC. Those ones don't have available updates.
