[CURRENT ISSUE] Sims 4 already running

I had put this off for almost a week due to midterms, but when I launched the new Windows admin profile today I didn't get the SDX error anymore, and I managed to finish the last week of the Reaper's Rewards event smoothly. So I then thought to myself if it works on the test profile let me try my main one again.... and my sims game launched. The only things that I noticed is the slower loading time (due to my mods) but other than that, I can actually play now?!

I'm a little confused because I didn't really do anything to fix it between my last post and this post, the only factor I could think of is that during the past week my PC needed to download and install 2 new Windows updates. Maybe that was the case?
