My game doesn't launch - EA app

Hi !

to make it short, my game doesn't start.

Shortly after Horse Ranch expansion pack launch, my game suddenly refuse to launch.
Off course, I had a lot of mods, so I backup all my EA Sims 4 folder (with my saves, and all) on another hard drive; but nothing change.

I tried to uninstall and reinstall only base game (EA app), launch the game from install folder (not through EA App), install it from Steam (base game) : nothing change..

When I start the game, there is this loading pop-in that open, the EA APP is reduce, and usually the game start shortly after that.
But now, instead, I'm back on EA APP, on my game page : no error message, no crash, nothing ... 
(I add dxdiag from today)

since Horse Ranch launch, I did all the update game, I even bought new add-on to try to fix the issue (look at that big  pigeon that I am - french expression).
I know that Horse Ranch has been launch a year ago, but I even bought a new hard drive to install the game on it to see if it fix something.

I tried to explain my issue on french help community, but no one seems to find a fix for me (you're my last chance...).
I'm desperate to play again one day (like really, it's been a year...)
Please, I really need your help...

Update : So it was EA App all along...
I tried to uninstall the app before but I just saw that it never fully delete everything.
So as a dirty person that I am,

• I delete the full folder by myself (there is a background task that you'll have to kill),
• download a new installer file and
• repair ea app through the installer (as it detect that EA is still installed)

And Voila, my game is starting just like that (I can only blame myself for loosing a year without trying that)
