what can I do, please someone help me, I have tried everything in the guides

If anyone could help me, I would be grateful, I don't want to lose my big family

first, I removed the mods before downloading, after downloading the update, I entered the game and got the error "content delivery error, error code 0000008:00000000000000c8" I entered the error in the search engine, it showed me that it was an internet connection error, I checked it and it works great. then I wanted to see if the gallery was working but it wasn't working and the error was shown this time: "The message has been damaged, do you want to repair it? Cancel/delete" and when I entered the game to see if I could play without the content being delivered, I couldn't save anything, the error kept popping up: "Error saving the game Error code: 21" what can I do?
