The Sims 4 will not Open :(

Hello Answer HQ! I've been having an issue with launching my game these past few days, and even after all my googling, I cannot seem to find something that will solve my issue. So now here I am asking for myself.

As of Friday (today, while writing, is Sunday) my game simply will not open. I literally cannot imagine why. Thursday afternoon I played just fine, everything ran like it typically does and I shut it down just like I always do (save and exit, shut off my PC), no funny business. Friday morning I downloaded some new CC, put it all in the folders and what do you know, my game will not open. Through either Steam (my usual launch) or directly the EA App, the game will start to run, and the "Preparing Game" bar will pop up and then disappear. And nothing happens. Just because of the age of my computer, I'm used to it doing that and then taking a bit to start but it has never taken more than maybe a minute to a minute & a half. However, even if I wait around 5-10 minutes nothing happens!

So, just a bit ago, I thought well. Geez it only started happening after some new custom content so let's see. I went through and took out all the CC that had not been in my game prior to this happening and put it on my desktop. I hoped there would be an issue and that I'd just have to go through the boring task of weeding out the problem. However, it has persisted. I'm going to try once more to take out all the items I hadn't used yet and see if leaving it long enough does anything. I might scream if I have to find a way to take everything out of the Mods folder to check.

(I've got rather low disk space and my computer doesn't enjoy it when I try moving mass amounts of files around to new locations where they don't fit. That's the only reason I haven't done that yet)

Thank you, and happy New Year if you're seeing this after today!
