@qimmig If there's a Sims 4 folder in Documents > Electronic Arts, please move it to the desktop. If it copies instead of moving, or you get an error when trying to move it, stop here and let me know.
Otherwise, try to launch the game after moving the Sims 4 folder. If it doesn't work, try pausing OneDrive syncing, which you can do by right-clicking the cloud icon in the lower-right corner of the screen.
If that doesn't help either, and you use a third-party antivirus, disable it, temporarily, and test again.
Thank you for your suggestions!! Unfortunately, I've tried all of them and the game still won't open. I forgot to mention in my original post, but I also took out all of the mods and custom content from my game and still, it won't open.
@qimmig Please create a new admin Windows account and try playing there. Make it local, as in, don't link it to your Microsoft account. You'll be able to (try to) launch Sims 4 without reinstalling anything, but your saves and other content won't be available. That can be addressed later; for now, just let me know whether the game works at all.
The game does work when I try it in that way, thank you. What do I do from here? Thanks a lot!
