Kiana171 Does a new save crash with no mods or custom content present? The question is whether the game is broken overall or just this save. And if only the save is broken, please try loading a different household, one you've never played before. You can use Load Game to jump to Manage Worlds and pick a different household.
If the new save doesn't work, try again but in a clean user folder. Move the entire Sims 4 folder out of Documents > Electronic Arts and onto your desktop. When you launch the game, a clean folder will spawn with no content. (Your saves and other content will be intact in the folder you've moved but temporarily unread by the game.) Don't add anything to the new folder yet; just start a new save and see whether you can load into live mode.
The Sims 4 errors in your dxdiag list ucrtbase.dll as the faulting module. This is a part of the Common Language Runtimes, as in, .NET, but if .NET were corrupt overall, the game probably wouldn't open at all. Still, if a new save doesn't work, we can look at that angle too.
