The Sims 4 won't load even to the main menu

Hi. So, basically the context is the following: 

Yesterday, I unlinked the OneDrive folder from my desktop which I didn't know it had all my important documentats (including The Sims 4 mods, saves and tray). Anyway, I even logged out from OneDrive trying to (supposedly) unsync all the files from my computer like a month ago, but it didn't. So, yesterday I delete them all by mistake, clicking on the OneDrive folder, that appeared on my desktop.

Luckily I had backups from the last time I play The Sims which was the day before yesterday (I use mods and cc) but everything was fine. However yesterday, after I deleted the OneDrive folders and couldn't restore them. When I try to start a new save (before and then after putting everything back) now it doesn't past to the main menu which it sucks. 

I repaired the game yesterday and nothing changed. I also, tried to uninstall it. The weird thing now, is that when I click on the Windows key (when the game gets stuck on the loading screen) I can't either get out by doing this. So, I don't get it cause it doesn't pop up a windows with any mistake.

Another important thing to consider is: I also tried (whenever I start the game again) to delete the localthumbcache and all that stuff. Besides the mods (overrides, custom content food, ui mods) etc that might be outdated from the backup I made regarding that folder.

My Game version is up to date and it says: 1.106.148.1030 

I need help ): I don't know what to do anymore. 

Thanks in advance!
