not able to resume sims games

when I join the sims game everything is normal, a notification pops up saying 'sims delivery error, an unknown error has occurred. then I press resume or resume any other saved game and it goes into the game but says 'save game: the game failed to save. please exit to the main menu and then click play to reload the game, error code: 22. I have done this and it didn't work. the game also asks what season to play in which is weird because I have already chosen it as it is a saved game that I've been playing for months. I pick the season, go into a world and all of the lots have warning signs above them saying 'sims cannot live on non-residential lots'. none of my old sims are there. if I try to make a new game I can go into create a sim but once I press play the game pauses. I went on last week and it was working again but since this update, it is broken again, removed all mods and cc. this is really stressing me out🙂
