Sims 3 Launcher suddenly wont launch anymore

Hey, 

a few months ago i was playing Sims on my laptop (see specs below). The next day it wouldnt work anymore.

When i click play or start the .exe the EA App briefly closes and reopens. I tried all of the stuff on the internet. I am not really a tech noob, so i really dont know what to do anymore. 

I dual boot with Linux/Fedora, i dont really use Windows 11 anymore, i just kept it for Sims, so me "destroying" something on windows feels unlikely.

Thats what i did:
1. Reinstalled several times, now only trying to install base game. When i tried installing Expansions it failed. When i clicked on deinstall in the EA App it brought me to the Windows App manager where i couldnt find the sims, so i had to delete all the folders, and also... (see 2. )

2. Cleaned Registry Entries

3) Reinstalled EA App several times

4) Tried Compatability Mode

5) Run as Administrator

6) Checked if all the MS C++ Redistributables and .NET are installed (They were and are)

7) Repaired Windows System Data with: sfc /scannow

8) Cleaned Cache in EA App, Sims 3 Cache (Did that before the first deinstall)

9) Deactivated Game Overlay

10) Repaired the Game

I dont know what to do anymore. Two evenings i wanted to play the sims that are gone now. My poor weekend. 

Thank you for any help.
