Cannot load any saved games

The game launches fine, but I cannot load into any saved games. I cannot resume my last game. I cannot load other saves. I get the same error every time (attachment). If I ignore the error and go to a world and try to load into a played family, the game stays loading indefinitely - I have to end the game from the task menu. (The game doesn't make it past loading screens.)

I play on PC. I just got the most recent update (Sept 18, 2024). I do not use mods or any cc.

I ran a few updates on my computer for drivers. I also repaired my game. Nothing is helping. I keep getting the same error.
