This really looks like a Mod issue (I've seen this before), but if you say that it's not.. Hm, please post a full DxDiag so I can check your specs better:

From what I see now it looks like you don't have the latest version of Windows 10, so please start by updating your computer 🙂
Having an old update usually means that updating drivers etc can be problematic too.
Just to be sure. If you move the The Sims 4 folder from C:\Users\Username\Documents\Electronic Arts\, then repair the game, then start it and make a new save, it still looks like that? I know you wrote that but please just try it in that order, it's so strange than that does not fix it.
Thanks for your reply!
It turns out, I may not have tried the right combination of the above to fix the issue. In the end I got it work by removing the Sims 4 file, repairing the game, and bringing everything back into the Sims 4 folder except for my saves. I am going to have to start a new save, but at least I got to keep my library in my tray files. When I brought my save files, it broke the game again.
Thanks, I consider this issue to be resolved now, despite losing some data.
