Help my sims 4 won't even launch ;-;

Vandamm593  The issue could easily be a certain kind of adult mod.  We can't really provide support for those (site rules), but if you want to go back to using it, the Sims After Dark Discord is a good resource.  Or you could install a fresh copy and see what happens.  Worst case, the game stops working, and you trash the new Sims 4 folder and let the game create another one.

Broken cc can also prevent Sims 4 from opening, although it's somewhat less common.

Anyway, I'm glad your issue is fixed now.
