Failed to launch error/Fully Black Screen when using CC

I found a fix for this it is a bit time consuming but I had to delete all my mods and redownload them via curseforge (I dont like curseforge ot adds unescasery files and causes the game to lag more then manually placing cc in the mods folder but its the only thing that has worked for me)  mcc and ui cheats also have an update so they work in game now and the creator of better exceptions has a hot fix aswell.  But basically I downloaded my mods back via curseforge (not macoxs as their cc us currently all corrupted even on curseforge) then I repaired the game via the ea app and then I had to restart my pc cause it was giving me the same error you have and then I immediately reopened the game and it worked. It might not work for everyone but it worked for me I think its something to do with curseforge automatically downloading into the mods folder instead of you manually placing them in.

5 hours of testing...

I came to the conclusion that the problem is not a specific mod or custom content (I tested them one by one). I realized that every time the game starts with some CC, when I test it again—even by gradually adding each piece of CC (including those that had already been tested and worked fine)—the game stops recognizing the custom content. It’s as if something in the game’s settings, or some file, keeps changing with each test. That would explain why a CC pack works perfectly one moment and then doesn’t the next.

I've noticed the same thing; with some cc I simply can't launch the game. Others I can, but after trying again, I can't launch anymore. 

I definitely give up, this is 100% EA's fault

So i basically was trying to set up the sims on my new laptop, and out of nowhere my app updates, then when i tried going back into my game i kept receiving a message saying there's an error on EA end that is causing the game to basically not open. If i remove the CC it opens, but i shouldn't have to take out 25,000 files just to play the game. The update literally broke the game. Almost like y'all released marketplace and broke our CC on purpose or something so we're forced to use it. I've been simming since way before 2014, and within the last year the sims has been so exhausting to deal with. I hope you guys are learning from these social experiments y'all call updates, ...

I cant even get the game to launch anymore even with trying a clean folder with nothing it only creates the save file with the autocloud file and thats it this is so frustrating

Listen, this is an EA issue.

I have taken 40 GB worth of mods/cc out and tested it piece by piece, package by package. There is literally no rhyme or reason that I can discern where start up fails or is successful - because it changes. Sometimes the same package will load successfully and other times the game won't even open - no change done besides deleting the thumbcache in-between running the game.

I can't even give you a list of problematic files, because it changes each time. Adding an AH00B hairstyle? Crashes the game. Delete the thumbcache and try again with no changes? It loads fine. And then it crashes again when I try a third time with just getting rid of the thumb cache.

I've verified the game files on steam. I've restarted my computer. I've deleted the resource.cfg.

The game is unplayable. Even without mods I am occasionally not even able to load the game - the process aborts itself and doesn't even try to load the loading screen.

I don’t have any of those mods (and honestly, I’ve given up testing them for now — besides, even the few mods I do have, only a couple from LittleMsSam, aren’t causing the error). The real problem is the custom content (CC). It loads with the game inconsistently — sometimes it works, sometimes it doesn’t. The issue is that I can’t realistically download more than 5,500 CC items one by one. That would take days, not to mention that many of them are only available on Patreon.

I just wish those last two updates didn’t exist anymore…

Hello, so my game is crashing when I click on it like within 5 seconds I have a crash text. I tried it without cc, and it opened fine but when I add even one cc it won't open. 

I’ve tested various MODs, but the launch is completely random—it works once, then fails with the same MOD. This isn't a MOD issue; EA’s reckless update broke the game. EA, please fix this ASAP.

this doesn't work for me!
