Failed to launch error/Fully Black Screen when using CC

I have removed all of my CC and mods numerous times, repaired the game, and every time I click on the play button I get a pop up that states "Failed to launch game"  An error on our end cause the launch to fail.  Try again a little later.  But it never stops, UNLESS I restart my entire PC.  Any help or suggestions please?

it is now DAY 3 of the game, not opening with cc. This is absolutely ridiculous. I have tried everything literally, and I cannot figure out for the life of me what is wrong.  PLEASE fix this, people put money in this game for it not to work because of a mistake EA made. Upset is an understatement.

I'm getting this same error. I've shared a link to my Electronic Arts folder in a DM to EA_Solaire. I hope that helps!

I created a new user folder as recommended. When I put Cas CC in it, the game wouldn't start and I got an error message. I've now sorted everything: Tattoos, Hair Accessories, Stuff, Jewelry, Default, Non-Default, Presents, Barts, Makeup. I just tested it three times and Sims started. Clothes and hair work for me. Maybe this will help others.

However, it's still very buggy. I still occasionally get an error message about a Lastcrash file. If I delete that file from the folder, Sims starts. It usually takes two or three tries before it starts. I've also tried removing it from different CC creators, but it's always the same. The problem is as described at the beginning.

I own every pack they have released since the beginning, even the kits, My base game was bought and then i bought the Deluxe version after, add that to the price of the packs, my game is worth about 2k GBP and i cannot play it like at all, it won't even start with any CC that i put in the mod folder's and as far as i can see, they are doing nothing about it, they have gone quiet....🤬

At this point they should roll back the updated. but that's a good idea, and they don't know what that means. 😆

The kitchen I was working on before the update broke my game 💔 im so devastated, as a pregnant woman on bed rest, Sims was literally the highlight of my day, im so fu****g pissed and disappointed 😞 

I have tried regenerating a new mods folder and copying cc files both directly into the mods folder with the scripts AND into brand new folders. It’s still not working. Plus I’ve tried all of the fixes below. 

ya and btw, back when games were sold as physical copies, I believe you purchased it, brought it home and then owned it. I don't get why when it's digital even though you are still purchasing a game and "owning" it, that means that the company can forcefully change what you own at any time free of consequence. Why does EA charge us to "own" the game and packs if at any time they can choose to alter it and make it unplayable? This business model makes no sense to me and I still don't understand how it's allowed. like this is Sims, not an online multiplayer game there is no reason for this many forced "updates" imo

I'm honestly just so sick of The Sims 4 atp. Sadly all thats been happening has kind of put me off of the Sims 2 and 3 as well just from the effort i have to put in to get the games to work.

I'm probably just gonna wait for Paralives to come out since the planned release date is around my birthday and I'm broke rn

  Hello, I have been having the same issue. I tried all day yesterday to see if it is a specific cc, but I don't think that mattered. Because if I deleted the files in the sims 4 files and cleaned it would go through to the main page; so, I can approve for the cc scripts, but when I logged out to go back in the "Error" would show up again. I have restarted/cleaned the folder. I have seen people say to take out the cache/online cache /local cache and nothing. Tired this morning and the same thing.
