xolauv Don't worry about the late reply. People show up when they have time to troubleshoot, and I answer when I can.
The fact that there's no new Sims 4 error means the game is being blocked from starting. It's not crashing, and apparently nothing else is crashing that would be taking the game down with it.
Did you check your antivirus for anything Sims 4-related? If you're not sure how to do that, try disabling it, temporarily of course, and repairing the game. As long as you don't do anything else at the same time, your computer should be safe, and you can reenable the antivirus as soon as you try to launch Sims 4 once.
If that doesn't help, create a new admin Windows account and try playing there. Make it local, as in, don't link it to your Microsoft account; you'll be asked to answer some security questions instead. Here again, disable the antivirus before creating the new account, and don't reenable it until you've tried to launch Sims 4.
If the antivirus is the problem, you can set exceptions for TS4_x64, TS4_DX9_x64, and TS4_Launcher_x64; or the Bin folder they're in. Add EADesktop.exe as an exception too.
If none of this helps, do you know someone with an EA account who would let you borrow theirs to test? The Sims 4 base game is free, so they wouldn't have to buy anything. The point is to see whether this is an account issue rather than anything on your computer.
