Lost sims 4 saves after updating Mac mini m4 to 26.2 Tahoe

Recently bought a M4 Mac mini and moved my Sims4 saves from the previous windows 11 install that I had been playing for many years. Every thing was fine and saving game progress was fine. I decided to do a system update in Sequoia the update finished but it was not actually an update to sequoia it was actually an upgrade to Tahoe 26.2 everything seemed fine until my wife launched the game the next day and had no option to load games so her saved games appear to be gone from the documents folder. I was told that the saves may have been moved to the iCloud Drive I checked and nothing appears to be there. I did nothing but choose update when I did this I did not select any options I was actually not given any to select anyway.  Also, my desktop which had been completely empty now was covered in files but they were years old and from a Mac that I had not used for years and it was in my office at the school I used to work.
