I disabled custom content and it told me that i had to restart my game, I tried but it wont let me back into the game, how do I do it without deleting my games?
You can't start the game after having removed the mods, or enabled them?
If you disabled them:
Remove them whole mods folder if you had mods. For example, move the mods folder from C:\Users\Username\Documents\Electronic Arts\The Sims 4 to your Desktop and start the game.
Then repair the game.
Open your Origin client and go to My Game Library, right-click The Sims 4 and choose Repair.
Also go to C:\Users\Username\Documents\Electronic Arts\The Sims 4\ and delete the file localthumbnail.package
If you can't activate the game after enabling mods then you have some that are incomatible with the new update.
If you want to double check you can remove them and see if the game works better. For example, move the mods folder from C:\Users\Username\Documents\Electronic Arts\The Sims 4 to your Desktop and start the game.
If you want to keep your mods, you can try some different things to sort out the ones not working:
If your problem occurred after a certain mod haul, remove all these new mods (see if the game works), and then add back a few at a time, restarting the game in between until you see the problem occurring again. Remember that you can possible have several broken mods.
If the problem started after the latest patch/update, always make sure to update your mods when you update your game. Check this list out for some mods that were broken in the C&D-patch! A few others have been broken after but not so many that there is a list. http://forums.thesims.com/en_US/discussion/928106/broken-mods-cats-and-dogs-nov-2017
Download Sims 4 Studio and do batch-fixes for your cc.
Search for the Mod Conflict Detector on google and run it, see if it can detect some broken/conflicting mods, remove these and try your game again. (Only detects conflicts between mods, not between mods and the game)
Like the first "solution", but for all your mods. Remove all and put back some at a time to find broken ones (last resort if you have like 1000 mods).
