Thanks for the help! It turned out one of my mods was corrupted so I just had to delete it and all my saves are back!
@KokoTempie Please try playing in a completely clean game folder: Drag your existing Sims 4 folder out of Documents\Electronic Arts and onto your desktop, launch the game to create a new folder, start a new save, and have a look around. If it's working, you can add any content you kept from your old game folder (saves, mods) to the new one. But don't add the contents of Tray, or at least first go in and delete the most recent entries, i.e. the files added when you downloaded the house from the Gallery.
If you still get a black screen even in a clean game folder, please run a dxdiag and attach it to a post.
