Sims 4 won't launch (EA APP)

So a few months ago, I came over to play some sims 4 and noticed the origin app was gone, and the EA app was in its place. Whatever, they function almost identically, and I bought the sims through steam anyways. 

It has only caused me issues.

This has happened before, and I have no idea how I fixed it.

Today I sit down to play the sims and everything runs fine! Until I take a bathroom break to return to a completley blank screen, besides my taskbar and the tab at the very top. It was completely unresponsive and wouldnt resize/minimize. I had to use task manager to use my computer. This part isn't completely unusual, the sims just crashes sometimes.

After trying to reopen the app, I was greeted only with a prompt from EA, "Your game failed to launch. An error on our end caused your launch to fail. Try again a little later."

I restarted my computer, nothing. Removed my mods folder, nothing. Repaired the game in steam, nothing. Tried a clean save, nothing. Deleted reshade, you guessed it, nothing.

I then realized that my copy of Deluxe Edition was missing, and the version I was 'launching' from the EA app was the Standard Edition.

Any ideas on how to help? I just want to play my stupid life simulation game.
