@madelf69 there is a technical issue currently which I've reported where there's an SDX notification when the game does a Quick Resume. So if you go into your console settings and then Groups>Quick Resume then remove the Sims 4 from the games on that list, that stops the false SDX message from appearing and causing problems for your game. If my game does a Quick Resume I immediately do a hard restart and switch my Console off, because I know I'm going to get the false SDX message.
I close my game down completely when I finish playing too, then go to my Xbox Series X home screen and then shut down from there too and that prevents a Quick Resume as well. I find if I switch off my Xbox from the Sims home screen it can automatically cause a Quick Resume the next time I put my game on.
You can also turn off SDX in your game settings, but as @jpkarlsen rightly says, we haven't had an SDX for some time. This is a technical issue, here's the thread:
