Sims won't start up (starts and then stops) with no error message.

I accidentally got my last post flagged as spam! Oops! 

But anyway, hello! I made an account just for this single problem I keep having with my Sims game after the updates back in February that made it impossible to launch; I gave up after weeks of trying to fix it. I decided to reinstall it after quite a few months; I updated it and hoped that it fixed itself. But nope.

I used to have an error pop up on my screen when I launched the game, but now there's no error code or anything to convey the issue. When I attempt to launch the game, it crashes when it barely even starts up and boots me right back to the EA App, with, once again, no error message.

Notes below of what happens and what ive done so far.

— Problem/ Result:

|| The game is clicked on and runs, whether it be from a shortcut, the Steam page, or the EA app. No matter where, it gives the same result; it will say that the game is running, and after only a few seconds, around 5 to 10, it immediately crashes and opens back up the EA App.

— What i've done / Extra: 

||The drive I use to put the Electronic Arts folder location at is in a considerable hard drive with about 600 GB of space, which should be plenty for the game's memory and space. Hence, I do not believe it is a space concern.

|| I've uninstalled the EA App completely along with The Sims 4 and wiped the game to a vanilla state; it did not fix it.

|| I've changed a setting when it came to my graphics card; it didn't resolve the issue either, and it no longer is a considerable reason anymore, as I no longer get an error message.

|| I've gone through the files to see if there's anything left in them that could be causing an issue, and they all read to be normal, except the last crash text file, as I don't read code that well and would need someone to evaluate it for me.

|| I checked the EA app, and although it is in a different drive, I don't see a single crash log pop up for the app itself; otherwise, I would've been notified.

|| I do not know if this is a memory issue with the game and not my PC, but I assume it likely isn't since the entire EA folder has been moved to a much bigger hard drive

|| I would also like to add (if this could benefit in any way) that I run on Windows 10 on an older PC; however, it should be compatible with the Sims, as I've played the game on this PC before in December.

I would deeply appreciate anyone who can help; I really want to play this game again, and I require the help that I can get. Please and thank you!
